Javascript uses function to create classes in two ways. 1. Use function classes. // MyFunction. jsvar CMyFunc = function () {// public method of the class for external calls this. func1 = function () {var I = 0; return I;} this. func2 = function () {_ privateFunc () ;}// private method in the class for the public method to call function _ privateFunc () {return 0;]} CMyFunc myFunc = new CMyFunc (); Usag
