Comments

Comments are statements that will not be executed by the interpreter, comments are used to mark annotations for other programmers or small descriptions of what code does, thus making it easier for others to understand what your code does.

In JavaScript, comments can be written in 2 different ways:

• Single-line comments: It starts with two forward slashes (//) and continue until the end of the line. Anything following the slashes is ignored by the JavaScript interpreter. For example :

// This is a comment, it will be ignored by the interpreter
let a = "this is a variable defined in a statement";

• Multi-line comments: It starts with a forward slash and an asterisk (/*) and end with an asterisk and a forward slash (*/). Anything between the opening and closing markers is ignored by the JavaScript interpreter. For example:

/*
This is a multi-line comment,
it will be ignored by the interpreter
*/
let a = "this is a variable defined in a statement";
