No it doesn't matter if you use Python or Java, in fact I recommend it. Most people will know how to read Python, but not always JavaScript. I made the switch because it can make it easier for me to solve problems, it's basically always accepted in interviews, most interviewers know how to read it, and when I'm watching videos a lot of them are in Python Answer from Weekend_Trick on reddit.com

r/leetcode on Reddit: Thoughts on using Javascript for Leetcode questions?

August 6, 2022 -

I'm a full stack web developer in Javascript with about 3 YOE and I'm trying to switch to big tech or a fortune 500 company.

I recently started LeetCode prep and been using JS as my primary language since I have the most experience with it. However, I noticed a lot of the LeetCode solutions in the discussions (especially the top ones) rarely use Javascript. The common languages I've seen are Python and Java. I'm wondering if these questions could be solved more concisely using Python or Java especially since Javascript lacks
some built in data structures (e.g. stacks, queue).

I'm thinking of switching to Python or Java. I had experiences with both in university, so I just need to brush up on them. However, I'm not sure if it's bad practice to use a programming language that you've never used in professional work or personal projects. Also, I'm not familiar with the expectations around this especially in big tech companies with DS/algo focused questions as opposed to domain focused interview questions. What have your experiences been on the expectations around this?

No it doesn't matter if you use Python or Java, in fact I recommend it. Most people will know how to read Python, but not always JavaScript. I made the switch because it can make it easier for me to solve problems, it's basically always accepted in interviews, most interviewers know how to read it, and when I'm watching videos a lot of them are in Python

I used to do Node (200+ LC solved with it) but switched to Python, and recommend you do the same. You'll notice no MANGA+ interviewers do Node so you'll be in an unnecessarily weird spot. There's also quirks with Node that bite you, and lots of tricks with Python you'll come across that make your LC life easier.

r/leetcode on Reddit: Javascript for leetcode

April 20, 2024 -

I use C++ for interviews and am now thinking of switching to Javascript as it is one of the languages I need to learn for my job and also, because it is a scripting language, the syntax is much more compact. I have been looking at data structures in Javascript and having a hard time figuring the equivalent DSs even after following multiple Javascript courses. Could someone, who uses JS for Leetcode give some pointers and where to learn more for the following: These are the ones that I couldn't find any obvious equivalent in JS.

Hashset : C++ has unordered_set and set for unsorted and sorted Hashset, JS ?
Hashmap: C++ has unordered_map for unsorted whose equivalent in JS seems to be just the 'object' data type. What about sorted map, sorted based on keys? like the C++ map.
Priority queue (min or max queue) that C++ supports

(As for custom structures like Linked list, tree etc, I would assume its just the custom object in JS?) Thanks :)

There’s a reason why people don’t use JavaScript for LC and use Python / Java instead

I use JavaScript for LeetCode and don’t run into many issues, although it took some time to learn how to apply it to this style of programming. JavaScript objects can be used as sets and dictionaries; to use them as a set, simply make the value in the JSON key/value pair some dummy value (0, false, etc.). But you also have the JavaScript Set: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set And Map: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map AFAIK there is no built-in priority queue or heap, but arrays also function as array lists (Array.push), queues (Array.shift) and stacks (Array.pop). Linked lists and trees are just pointers bundled with data; you don’t need built-in data structures for them, although you can create your own classes that mimic the behavior from OOP languages. You can cache the necessary nodes (dummy, head, tail, root, etc.) and perform the typical operations in a function. But it’s true that you will need to write your own classes for certain questions that require something like a heap, which can be problematic if your interviewer won’t let you copy and paste these classes when needed.

r/leetcode on Reddit: Does anyone use JavaScript for LeetCode

I just participated in the weekly contest.

There is like zero solutions in JS except mine. (In the solution section)

Why? Shoud I switch? (I use JS at work)

python is just very convenient for leetcode, it comes with so much that's either included or is one import away that it simplifies most problems a fair bit.

I use TypeScript (basically JS) for LC. I wouldn't worry too much about the language you use though. If you don't know a programming language, then python tends to be a good option because the syntax is simple and there are some automagical methods/syntax that make it ideal for translating concepts into code. But at the end of the day, LC type problems are 80% concept and 20% language. Not worth spending so much time learning a new language for the sake of solving LC.

r/learnjavascript on Reddit: 30 Days of Javascript LeetCode good for a beginner to learn?

August 1, 2024 -

I have some knowledge in Java,C,Python

I recently started watching Coding Train, and really found his topics (p5.js) interesting, so I decided i wanted to learn JS. From what he did in his videos, its not that different to Java, C or Python, most of the practices are similar.

However, i started the Leetcode 30 days of Javascript, am on the 2 question and already completly lost. JS suddenly seems so different to other languages, people are using weird syntax ive never seen before**.** one thing that tripped me off especially was "toBe: (val2) => { toBe: (val2) => {" on the 3rd question

Is that course good to learn JS?

Are ther any other resources to learn JS that you could recommend more?

i havent looked at it, but leetcode is for experienced devs practicing for interviews

people saying they haven’t looked at it is crucial to answering your question. The Javascript specific questions on leetcode, like 30 days one , are actually a pretty good way to learn some of the nifty javascript things. I just completed it and can say that I have a much better understanding of Promises, Closures, async await syntax, event handling, timing AND more. It’s even got a typescript option to help you with that. Personally I think it’s good, as long as you really understand every single part of the solution. Coming from another language can be quite difficult, so it’s important to really hammer in the functional programming concepts

Currently a sophmore taking Computer science principles and we are still barely learning anything, loops, while, etc. functions, Can using leetcode be effective as a beginner? If so, where should I start.

Thanks everyone!

Maybe, but I really like freecodecamps JavaScript path. Includes data structures so if you’re a beginner maybe start there

If you want to learn JavaScript, leetcode would be a wrong choice. Sure you will learn loops, variables, basic data structures etc but yea that's it. It won't teach you how to fetch data from a server or build interactive UI. If you're new to Web Development you can start here

r/leetcode on Reddit: Switching from Javascript to Python in order to grind Leetcode, what’s the best resource to learn the intricacies of the language?

I’ve been working as web dev for a few years, all JS/React based. Now I’m starting to learn DS&A and do Leetcode and I’m realizing that I’m not doing myself any favors trying to stick with JS when solving these challenges, so I decided to learn Python.

All the Python courses I see are about learning to program from scratch. I’m not interested with that, I just wanna familiarize myself with the syntax and understand how it’s different from JS.

Is there any Python course as a 2nd language? Meaning that’s tailored for already experienced programmers?

Any advice for someone in my particular situation?

I switched from js to python to solve leetcode problems(which was great). It ain't that hard. You just need to learn how to use data structures. You don't need any tutorial/course/book for that. Just follow these process: 1)Start by solving easy problems that require minimalistic code 2)Ask from chat gpt about how to do certain python operation(such as creating array, popping element from stack) 3)If you get syntax error, ask again it from chatgpt about this issue 4)After solving problem, look at solutions, and learn how other people solved it.

Well you should go to javatpoint website they have python section try to skim over that see if you can get familiarized with the syntax. Also go to hacckerrank python they have structured it from basics to advanced so you can practice

r/leetcode on Reddit: Is it okay to do LC in JS?

August 13, 2024 -

I have started doing leetcode recently. I used to do it 2 years ago and now I wanted to brush up DSA skills but the issue is I have forgotten a lot of Java since I only learnt it back when I first started LC. I have worked on JS for the past 4 years and I am more comfortable in it. I have heard stories that the interviewers don't like languages other than cpp, java and python. Is it true?

You can, but compared to python, you’ll find a bit of bottlenecking since somethings like heap and default dicts etc are part of the standards libs unlike js where you’ve to implement them from scratch. Other than that, I don’t see a reason not to use JS for DSA especially coming from a FE background

Cleared Amazon and MSFT just using js. I’m a full stack dev though

I am a web developer in React, so I'm proficient in javascript and now I want up my game so that I can crack big product company. For that DSA is required. Should I prepare DSA with javascript or I have to learn c++ or python. C++ or python path looks difficult since I don't have knowledge of them, I have to learn from scratch.

If you already know that the companies/positions you want to target use C++ or python it probably can't hurt you to learn them. But if you just want to get better at the problems I would stick with a language you know.

Using JavaScript is fine as long as you are working through the problem. That said, I would also recommend learning other languages, simply as a way to help your fundamental programming skills grow, which is the same reason I use leetcode in the first place.

I personally think that work productivity is about taking the easiest/fastest way to solve a problem, but more personal growth takes place by taking more of the hardest/slowest way to solve a problem.

I’ve exclusively done leetcode in JavaScript bc I could kill two birds with one stone as I am also learning full stack web dev.

Anyways, the OA from Optiver does not let you use JavaScript! The only options were python, c++, and Java.

Is it time to switch languages? I had everyone on Reddit assuring me to just pick whatever language and that it doesn’t matter only to get met with this. Damn.

Just learn python, it’s should be relatively easy if you already know how to code in any language.

It says on their application: Experience writing software in C++, C#, C, and/or Python, surprised they give Java actually

Do you think it's a bad idea to solve problems in JS? I've been doing lots of frontend programming recently and I really enjoying writing code in JS so I thought I'd solve LC problems in JS and I'd interview in JS. Or should I switch to a different language?

I’ve actually been in multiple FAANG interviews that didn’t allow JS. I’d say python is the safest choice.

I’d say Javascript is safe if you’re looking for frontend positions.

r/leetcode on Reddit: javascript as a language of choice for interviews

December 28, 2023 -

As the title suggests. Honestly I use it every day for work so I'm most comfortable with it and Typescript style languages. Kinda not super enthusiastic about using Python, however you apparently are asked to code heaps from scratch in interviews now when it comes to JS? Is this true? Advice? Should I just switch to Python (groan)?

Ha does not have a built in heap. Implementing it on your own is not too bad, you just gotta memorize it. But using a language that has all the data structures already built in would be the best. I got burned by heaps during coinbase interview. Now I use golang for interviews.

I would think if an interviewer wanted to see if you can implement a heap they're not just going to let you use a builtin one if you're using python. Otherwise if you're just coding on a whiteboard or something I would expect that you can pretend that you have a heap already written or from a library. Also you can just learn how to write one if you're worried about it, it's not that tricky.

July 16, 2021 - Well let's say for full stack interviews since you don't want to limit yourself. I don't see why you can't use pseudo code if asked about a heap ... If it's front end, I can guarantee they will test your JS skills thoroughly one way or another. I'll stick with JS or TypeScript. ... I say use a language you’re comfortable with. A lot of Leetcode questions aren’t common outside of interview and are there to verify your knowledge of DSA, not specific programming languages.

r/leetcode on Reddit: Why not Javascript for DSA interviews?

May 1, 2022 -

Hi all , i am working as a Frontend dev , and my daily work includes coding with Javascript...

The question asked by a fellow about choosing the language for DSA gave responses majorly Cpp and Python...

I know Cpp and STL but i would like to use Javascript for further practising DSA instead of using one lang at work and one for leetcode...

Should i start with JS as i am proeficient in it ? Or should i go with Cpp which is more imperative and gives more control over the code ?

Use the language you are most comfortable writing. Algo problems are mentally taxing. Having to remember syntax could cause you to perform worst than you would when writing JavaScript. If you’re concerned about the lack min/max heap implementation in JS, then you can always write a heap class and store it in a repl.it. If you’re posed with a question that requires a heap to solve optimally, just ask for the interviewer’s consent and pull the heap class code from the repl.it.

Not sure who said not, I've interviewed many candidates and they SHOULD use the language they are most comfortable with. The only downside of JS is that it does not have native implementation of heaps, but that's about it.

r/leetcode on Reddit: Frontend Dev - Javascript vs Typescript

May 2, 2023 -

Hello everyone, I am currently a Frontend developer and about to start my journey on Leetcode.

The reason that I start Leetcode is to prepare for interviews.

I am just wondering which one should I start with - js or ts.

I use Typescript the most in my project/work.

1.)One thing I concern is that, when it comes to interviews in the future, is there always an option to use Typescript? What I am afraid is that the interview only allows you to use javascript instead of typescript.

2.)I am also concerned about the numbers of solution - javascript versus typescript

Any advice?

Regarding number of solutions - I don’t think I’ve seen any official editorial use JavaScript. As far as I’m aware they generally use Python, Java, C++. Unless you’re talking about unofficial solutions. If you’re practicing for leetcode style interviews, might as well go for JavaScript since it’s a tad faster. I think the value of typed language comes in when you’re writing more than a script’s worth of code, for example, in OOP. I personally use Python if you’re open to that. I think it’s rare that leetcode styles interviews don’t let you pick a language - but then again I’m not a pure FE SWE.

neetcode has a video describing why he does leetcode in python - the built in data structures are superior and the syntax is easy enough to pick up. https://www.youtube.com/watch?v=0K_eZGS5NsU&ab_channel=NeetCode You will probably get more value out of learning python than trying to learn some TS that doesn't really benefit leetcode solutions.

r/cscareerquestions on Reddit: Java vs JavaScript for doing leetcode?

March 3, 2019 -

I have about 7 months of experience, working as a front end developer. Java has been my language of choice for leetcode, and I'm way more comfortable with it. I'm guessing it's also one of the most used languages in the leetcode community, so it's much easier to compare solutions and stuff. The issue is, my work experience has mostly been in JavaScript ( React and backbone) , and I have nothing to show for in Java. Will the interviewers be okay if my experience is in JavaScript, but I solve the problems using Java?

they won't care

I dont agree with the other comments stating " they dont care ". IF you are applying for FRONTEND roles you MUST be able to solve leetcode in javascript . I gave my fb frontend internship interview a couple of months back and the interviewer straight up told me he would prefer to see me write code in javascript.

r/cscareerquestions on Reddit: Front-End Developers on this sub, do you do Leetcode in JavaScript or Python?

January 25, 2020 -

Obviously, most FED interviews are focused on JS, and I'm assuming that if you are applying for FED positions at FANG / Unicorns / Big N / Large tech companies, then you are specializing in JS.

However, I keep hearing that Python is THE best coding interview programming language.

So assuming that we know JS + Python equally well, but we specialize in JS for the actual role, which one would you use for the coding interview, or would you just use BOTH: JS for any Web-based domain specific questions and Python for general Leetcode-style algorithm CS concept questions?

Do the interview in the language you're most comfortable in.

Don't try to optimize for some higher ideal of "interview perfection." Being uncomfortable shows. Being desperate for points shows.

Go in, treat the interview like you don't give a damn whether you'll pass or not, and just try your best using your best tools.

TypeScript, it's like JavaScript for grown ups.

But what do I know about interviews? I don't apply for jobs, jobs apply for me.
