JavaScript best practices

Since JavaScript is a programming language, it is important to follow good programming practices in order to obtain quality and maintainable code. There are many ways to do JavaScript. Here are some of the best practices for writing quality JavaScript code :

1. Use meaningful variable names

It's essential to use meaningful variable names so that other people can understand your code more easily. For example, if you have a variable that contains the price of a product, you can call it “price” or “product Price”, not “p” or “x”.

2. Use comments

Comments are very useful for explaining what your code is doing. They can help others understand your code, and they can also help you remember what you did when you come back to it later.

3. Properly indent your code

Properly indenting your JavaScript code will make it more readable and easier to maintain. For example, if you have a function that does multiple things, you can indent all the lines of code that belong to that function to separate them from the rest of the code.

4. Use standard naming conventions

There are many standard naming conventions for variables, functions, classes, etc. By following these conventions, you make your code more readable and easier to maintain.

5. Do not put unnecessary code

Unnecessary code makes your code harder to understand and maintain. If you are not using a variable or a function, it is better to delete them. Also, if you just add code for no reason, it will make your code harder to understand.

6. Always test your code

It's important to always test your code to make sure it works as expected. You can use automatic testing tools, but it's also important to manually test your code.

7. Follow W3C standards

The W3C is the standards organization for the World Wide Web. By following W3C standards, you ensure that your code is compatible with the most popular browsers.

8. Use the right libraries

There are many JavaScript libraries available, each with their own pros and cons. Choose the libraries that best suit your project.

9. Optimize your code

Optimizing your code can help improve the performance of your website. However, it's indispensable not to sacrifice the readability and maintainability of your code for minimal performance gains.

10. Respect copyrights

It is essential to respect copyrights when using JavaScript code. For example, if you're using code from a website, be sure to read the terms of use before using it. Also, if you create JavaScript code, be sure to share it with others respecting copyrights.
