JavaScript Algorithms and Data Structures (Beta) - JavaScript - The freeCodeCamp Forum
August 27, 2024 - Im going back and catching things up because I skipped the current curriclum if I covered it in the legacy challenges before the switch. So I`m getting to the shopping cart, platformer game and dice game and it seems to go from a step by step format to writing complex coding at length, Just ...
“Legacy JavaScript Algorithms and Data Structures” vs “JavaScript Algorithms and Data Structures (Beta)"
We've gotten a lot of feedback that the Beta course needs more repetition, and a smoother ramp-up. We're working on adding a few additional projects to make it easier for beginners. I still recommend doing it over the old JS cert, but as many folks have said here, it doesn't hurt to do both for extra practice. More on reddit.com

May 14, 2024JavaScript Algorithms & Data Structures Certificate VS JavaScript Algorithms & Data Structures (Beta)
You can start from the beta course. I completed both of those courses and I find the beta version much better, and if you watch videos on FreeCodeCamp YouTube explaining basics of JavaScript and then do the practical course it's a game changer. My suggestion is don't follow along any tutorials where you build projects, you waste a lot of time and learn very little, but if you watch the videos where basics are explained and then follow the practical course and then try to build something on your own then it's time well spent. I have regrets that I didn't do this when I started to code. I was in tutorial hell and about to give up until I found FreeCodeCamp and it changed my perspective. More on reddit.com

January 9, 2024Best way to learn JavaScript Algorithms and Data Structures (Beta)
You really need to have a solid foundation with HTML and CSS before jumping into Javascript, so definitely go through the Responsive Web Design Certification courses first. I'm about halfway through the Web Design program and I love it. I've jumped around between a few different online courses for HTML/CSS/Javascript and imo it's a much better program than others I've seen and tried elsewhere. It's very in-depth and while it does hold your hand at the beginning, at a certain point it forces you to critically think/research a bit on your own to find solutions which actually makes you learn it properly instead of just going through the motions of copying code.

Which one do you suggest better to learn in 2024 ?
“Legacy JavaScript Algorithms and Data Structures” course or “JavaScript Algorithms and Data Structures (Beta) course” ?
because the beta course looks like an improved iteration and it might offer updated content and better learning experiences.

There's no reason not to try a bit of them both and see which one suits you better. I personally prefer the style of the legacy course, but new one has a lot of good updated content and some people like the format much better.

Any idea? which course should be taken first?
As freecodecamp says courses should be taken in order, but a while ago "JavaScript Algorithms & Data Structures Certificate" was 2nd on the list after the "Responsive Web Design Certificate" course, but now I see "JavaScript Algorithms & Data Structures (Beta)" 2nd on the list.

The new course is intended to replace the old one. It was released fairly recently and may still have some bugs and rough spots, which is why it's identified as "Beta" for now. Eventually the old course will be removed from the platform (but not for quite a while, giving everyone who is already working on it plenty of time to complete it).

December 30, 2023 -
Hi, so I started going through the JavaScript Algorithms and Data Structures legacy version before the beta came out and it was straightforward because they gave you a tutorial on the subject you were learning. Now in the new beta version they are implementing CSS and HTML and offering no tutorial on how to do things. What is the best way to go about completing this course? doing a CSS HTML intro before the javascript course? or just going along and googling everything as I'm doing the course?

The freeCodeCamp curriculum is designed to be done in order, so any course you do will assume that you already have knowledge from the previous courses. The previous JavaScript course didn't directly include any HTML and CSS, and you can continue to complete that material. It is at the bottom of the curriculum page, labeled as "Legacy". Completing those projects will still allow you to claim the JavaScript certificate. If you plan on doing any of the other web-related content, you are going to need HTML and CSS though.
