JavaScript Object Literal An object literal is a comma separated list of name value pairs wrapped in curly braces. In JavaScript an object literal is defined as follows: var myObject = { sProp: 'some string value', numProp: 2, bProp: false };

Literal means fixed value in source code. In ECMAScript scripting language its possible to represent object as literal. e.g. 

  var newobj = {
  var1: true,
  var2: "very interesting",
  method1: function () {
    alert(this.var1)
  },
  method2: function () {
    alert(this.var2)
  }
};
newobj.method1();
newobj.method2();
