JSDoc is a powerful tool for documenting your JavaScript code. It helps you keep track of your functions, variables, and more, making it easier for others (and your future self!) to understand your code. In this article, we'll show you how to take your JSDoc documentation to the next level by adding real code examples right within your comments.
When you're writing JavaScript code, adding JSDoc comments is a great practice. It's like giving your code a friendly tour guide that explains what's going on. But what if your code is a bit tricky, and you want to include a real example to show how it works? That's where adding real code in your JSDoc documentation comes in handy.
To add real code examples in your JSDoc comments, you can use the `{@example}` tag. This tag lets you write out a code snippet that will be displayed in the JSDoc documentation. Here's how you can do it:
/**
* A function that adds two numbers together.
* @param {number} a - The first number to add.
* @param {number} b - The second number to add.
* @return {number} The sum of the two numbers.
* {@example}
* // Example usage:
* const result = add(5, 3);
* console.log(result); // Output: 8
*/
function add(a, b) {
return a + b;
}In this example, we have a simple `add` function with JSDoc comments that include an `@example` tag. Inside the `@example` tag, we have a code snippet that shows how to use the `add` function with two numbers and then log the result to the console.
By including real code examples in your JSDoc comments, you're not only documenting your code but also providing practical usage examples for anyone reading your documentation. This can be incredibly helpful for understanding how your code works and how it should be used.
When adding real code examples in your JSDoc comments, remember to keep the examples clear and concise. Focus on showcasing the key aspects of your code and how it should be used. Avoid including overly complex or unnecessary code that might confuse readers.
In summary, adding real code examples in your JSDoc documentation is a fantastic way to make your code more accessible and user-friendly. By using the `{@example}` tag, you can provide practical examples that demonstrate how your code works in action. So go ahead, take your JSDoc documentation to the next level by adding real code examples today!
