Key Points About JavaScript Style Guide
Writing JavaScript code in a way that's readable and understandable is an important point that every developer should pay attention to. It's worth considering that your code should be understandable both by computers and by humans. Therefore, having a suitable writing style can be very effective. This writing style should include specific points such as logical use of variables, new lines, and use of meaningful comments.
Why is Style Guide Important?
The style guide can help you ensure that your code is clean and maintainable. When you and your team follow a stable style guide, the code you write will be more understandable and easier to maintain. This topic is also important from the perspective of programmers because clarity in code helps to proceed with tasks more quickly and efficiently.
Using Variables and Functions Correctly
Correct use of names for functions and variables is very important. Names should be clear and precise so that others don't need to refer to additional details to understand them. Also, it should be noted that larger variables should be divided into smaller, more manageable segments.
Rules and Best Practices

- Maintain consistent indentation.
- Instead of
var
, use let
and const
.
- Use meaningful comments and clarify your code.
