In this case, showing both a good example and an anti-example will benefit the reader. For example: # A valid string assignment. s="The rain in Maine." # An invalid string assignment because of the white space on either side of the # equals sign. s = "The rain in Maine." A good sample code set demonstrates a range of complexity.

October 20, 2025 - Code examples should be short and should ideally only show the feature you are immediately interested in. Write your code to be as understandable as possible, even if it is not the most efficient way to write it.

Some tips and tricks how to write code examples that educate and entertain.

July 3, 2024 - The image below is an example of self-documenting code: The function and variable names clearly convey their meaning and purposes. ... Ensure your comments are clear and easy to understand. Write comments that are concise, clear, and easy to understand. Avoid jargon unless it's necessary and well-known in your field.

July 8, 2021 - I spent 2 hours taking a real problem I had this week, making sure I understood what was actually happening with the CSS, and making it into a minimal example. In the end it “just” took 5 lines of HTML and a tiny bit of CSS to demonstrate the problem and it doesn’t really look like it took hours to write.

February 24, 2023 - For example, a function that creates a file, writes to it, and sends an email at the end shouldn’t do all that within itself. Each method must have its responsibility and be called within the function.

March 27, 2025 - Here’s a basic program written in a few different OOP languages—this example is the most basic program to write, called “Hello, World,” and it’s something programmers often use to get an idea of a language’s most basic features. First, create a string and give it the value: “Hello, World” · Now, let’s do something with this value by writing it out onto the screen somewhere (NOTE: This isn’t about understanding all of the code, it’s just to take notice of their similarity).

June 24, 2022 - Code examples illustrate how to use a programming element to implement specific functionality. They might include: Simple, one-line examples interspersed with text. Short, self-contained examples that illustrate specific points. Long samples that illustrate multiple features, complex scenarios, or best practices. ... Assess a technology through its API during planning. Learn or explore a language or technology. Write and debug code.

Get started by writing code examples to learn the basics of the C# syntax.

November 5, 2024 - Separate Logic: Write core functions yourself whenever possible. This way, if you ever need to remove a dependency, it won’t break your code. Let me give you an example with our previous Nodemailer code to implement the concept of separating logic in your code.

Skipping redundant code using ellipses (…) is necessary to keep examples short. Still, writers should do it thoughtfully as developers frequently copy & paste examples into their code, and all of our code samples should be valid JavaScript.

May 4, 2023 - In the good code example, we simplify the function by passing in a user object and using a simple conditional statement to check the length of the name. Readable code is easy to understand. Use consistent formatting, indentation, and spacing. Write comments to explain what your code is doing.

March 11, 2004 - So one of the things I do is to keep everything else simple and out of the way, which means I avoid using other patterns if they are likely to cloud understanding of the core issue, even if you'd use those patterns in a real system. An example of this is in the object-relational mapping patterns in P of EAA. I show a lot of mapping patterns (such as Foreign Key Mapping) where I hard code the data transfer between objects and database.

Answer (1 of 3): What programming language? How complex? I mean, if you just want to “see code”, go to github -> explore -> trending. There is a LOT OF CODE THERE. But without knowing what you want it is HARD to help you. Like, there is a lot of code out there.

I have attached my code, so if there are better ways of doing this. Please comment on it. //Initialize the array that will hold the primes var primeArray = []; /*Write a function that checks for primeness and pushes those values to the array*/ function PrimeCheck(candidate){ isPrime = true; for(var i = 2; i < candidate && isPrime; i++){ if(candidate%i === 0){ isPrime = false; } else { isPrime = true; } } if(isPrime){ primeArray.push(candidate); } return primeArray; } /*Write the code that runs the above until the length of the array equals the number of primes desired*/ var numPrimes = prompt("How many primes?"); //Display the finished array of primes //for loop starting at 2 as that is the lowest prime number keep going until the array is as long as we requested for (var i = 2; primeArray.length < numPrimes; i++) { PrimeCheck(i); // } console.log(primeArray);

February 13, 2023 - Let’s say you’re writing a ... of those prices. For example, you give it [13, 28, 17, 143, 184, 72.3] and it should return “The average price for 6 widgets is $72.22.”...

September 11, 2024 - This example uses a concise arrow function and regex to count the number of vowels in a given string. While the code is very short and easy to write, it may not be immediately clear to other developers how the regex pattern works, especially if they are not familiar with regex syntax.

August 23, 2021 - Writing a good code sample Authoring a good code sample is hard. Let me clarify that, putting together a sample that demonstrates the usage of an API, or shows off a UI idiom, can be quick and easy …

As I mentioned earlier, I believe that most of technical writing benefits from interactive examples. So I've built and open-sourced Codapi — a platform for embedding interactive code snippets virtually anywhere.
