JavaScript Literals

JavaScript Literals are the fixed values, which are constant in nature throughout the program execution.

  • String literals must be enclosed with single or double-quotes.
  • Number literals must not be enclosed with quotes.
var name = "Jack Sparrow";    //String literal "Cheese" is enclosed with double quotes.
var address = '123 ABC STREET';    //String literal "address" is enclosed with single quotes.

var id = 1001;    //Number literal "1001" is not enclosed with quotes.
var price = 120.25;    //Decimal literal "120.25" is not enclosed with quotes.

Overall

JavaScript literals are the values that remain constant throughout the program execution.
