Adding Comments to JavaScript Code
Adding comments to JavaScript code is a great way to explain and document the code that you are writing. This makes it easier to read and understand, which is especially helpful for others who may need to work on the code in the future. Comments are also a great way to make a note of something that needs to be done, or to remind yourself of why a certain piece of code was written.
Comments in JavaScript are denoted by two forward slashes (//). Anything that follows these two slashes is considered a comment, and will be ignored by the interpreter. For example:
// This is a comment
var x = 5; // This is also a comment
In the code above, the first line is a comment, and the second line contains a variable assignment followed by a comment. In both cases, the interpreter will ignore the comment and only execute the code.
In addition to single-line comments, it is also possible to create multi-line comments in JavaScript. This is done by wrapping the comment in slash-asterisk (/*) and asterisk-slash (*/). For example:
/*
This is a multi-line
comment in JavaScript
*/
var x = 5;
Comments are a great way to make your JavaScript code more readable and understandable. They can also be used to remind yourself of why certain pieces of code were written, or to make notes about things that need to be done. If you are writing code for others, comments can be helpful for them when trying to understand what is happening. With a few simple lines, you can make your code much more understandable and easier to work with.
