Javascript Comments

Comments in JavaScript are used to explain and document your code for yourself and others who may read it in the future. Comments are ignored by the JavaScript engine, so they don't affect the execution of your code.

There are two types of comments in JavaScript: single-line comments and multi-line comments.

Single-line comments start with two forward slashes // and continue until the end of the line. Here's an example of a single-line comment in JavaScript:

// This is a single-line comment

Multi-line comments start with /* and end with */. They can span multiple lines and are often used for longer comments or to temporarily disable code during development. Here's an example of a multi-line comment in JavaScript:

/*
This is a multi-line comment
that spans multiple lines
*/

You can also use comments to temporarily remove code during development, without actually deleting it. This can be useful for testing or debugging purposes. To do this, you can simply add a comment around the code you want to disable:

// This code is currently not being used
// myFunction();

In general, it's a good practice to add comments to your code to help yourself and others understand what it does and why. However, it's also important to keep your comments up-to-date as your code changes, to avoid confusion or errors.
