Chaining JavaScript methods

JavaScript allows us to invoke multiple methods on an object in a single expression. This is called chaining and is accomplished by stringing the method calls together with dots between them,

NOTATION:

object.method1().method2().method3();

EXAMPLE

 1) account.number("012477630").setBalance(10971).applyCredit(200);

            [IN SIMPLE MANNER] 

 2) $("#myDiv").removeClass("off").addClass("on").css("background": "red");
