In JavaScript programming, comments are crucial to the readability and maintainability of code. Comments can help other programmers understand our code logic, implementation methods and some details, and they can also help us review our own code. JavaScript comments mainly include single-line comments and multi-line comments. Single-line comments start with two slashes (//), while multi-line comments start with a slash and an asterisk (/), and an asterisk and a slash (/)Finish.
