What are comments in javascript?

 

 

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.”);
