How to Add Comments in JavaScript
Comments in JavaScript or in any other language are used to describe and explain the code. Comments make it easier for other developers to understand and maintain the code. There are two ways to add comments in JavaScript:
- Single Line Comments
To add a single-line comment in JavaScript, use two forward slashes (//) at the beginning of the line. Like this:
// This is a single-line comment in JavaScript.The interpreter will ignore everything after the double forward slashes and treat it as a comment. Single-line comments are useful for adding quick explanations or reminders.
2. Multi Line Comments
To add a multi-line comment in JavaScript, use /* to start the comment and */ to end the comment. Like this:
/* This is a
multi-line
comment in
JavaScript. */
The interpreter will ignore everything between the opening /* and closing */ and treat it as a comment. Multi-line comments are useful for adding detailed explanations or for temporarily disabling a block of code.
It’s important to note that comments do not affect the code’s behavior, and the interpreter will ignore them. Therefore, it’s essential to keep your comments up-to-date and relevant to the code they describe.
In nutshell, to add comments in JavaScript, use // for single-line comments and /* */ for multi-line comments. Well-commented code helps make it easier for other developers to understand, modify and maintain the code
