How does JavaScript add comments?

Comments are important in project development, and reasonable code annotations facilitate later modification and maintenance of the project and make it easier for co-workers to understand the functionality of the piece of code. W hen the browser is running, the comments are not read. Today we're going to learn how JavaScript adds comments.

Single-line comment: In JavaScript, a single-line comment is represented by // (double forward slash). as follows:

//这是一个单行注释

Multi-line comments: Multi-line comments in JavaScript */ included in /* and /**/ slash with asterisk). as follows:

/*这是一个注释*/

Or as follows:

/*
*w3cschool-编程狮
*随时随地学编程
*/

That's all JavaScript says about how to add comments.
