JavaScript comments are used to add notes, explanations, or documentation to the code. They are ignored by the JavaScript interpreter and do not affect the execution of the program.
There are two types of comments in JavaScript:
Single-line comments: These start with two forward slashes (//) and continue until the end of the line. Anything following the slashes on that line will be ignored.
// This is a single-line comment
var x = 5; // This is also a single-line comment
Multi-line comments: These are used to comment out multiple lines of code. They start with a forward slash and an asterisk (/*) and end with an asterisk and a forward slash (*/).
/*
This is a multi-line comment
It can be used to comment out multiple lines of code
*/
JavaScript comments are useful to keep your code organized and readable, they make it easier to understand the code when you come back to it after some time, also they are helpful when working in a team of developers, as they can provide context and explanations for the code. Comments should be used sparingly and only to provide important information that is not evident from the code itself.
