JavaScript supports the following two different ways of commenting.

  • single line comment
  • multiple line comments.

    Single line comment

  • // This is a single line comment.
  • Any text between // and the end of the line will be ignored by JavaScript (will not be executed).

Example of single line comments

//This is a single line comment

alert(“We are learning JavaScript single line comment”);

//alert(“Good Morning”);

Multiple line comments

  • In JavaScript multi-line comments start with /* and end with */.
  • Any text between /* and */ will be ignored by JavaScript.

Example of multiple line comments

/*Multiple line comments start here

alert(“Good Morning”);

Multiple line comments end here*/

alert(“We are learning JavaScript multiple

line comments.”);
