Date: 2009jul22 Updated: 2018jan25 Language: javaScript Keywords: OOP, OO, class Q. Can you explain Object-Oriented javaScript? A. ECMAScript 6 added real support for clases. Until it is widely available use these tricks. There are other tutorials on the web but I find most of them too verbose. Here's the short answer. UPPER_CASE names are selected by you.

function CLASS() { var PRIVATE_VARIABLE; // This variable can NOT be accessed from outside the class const PRIVATE_MEMBER_FUNCTION = function(param1, param2) { // This member function can NOT be accessed from outside the class // Do stuff }; // <--- Note the semi-colon! const CONSTRUCTOR = function() { // Do stuff }; // <--- Note the semi-colon! this.PUBLIC_VARIABLE; // This variable CAN be accessed from outside the class this.PUBLIC_MEMBER_FUNCTION = function(param1, param2) { // This member function can be accessed from outside the class // Do stuff }; // <--- Note the semi-colon! CONSTRUCTOR(); // Call the private member function called CONSTRUCTOR to initialize }; // <--- Note the semi-colon! CLASS.STATIC_METHOD = function(param1, param1) { // Do stuff }; // <--- Note the semi-colon! // That's it. // Example use: var a = new CLASS; a.PUBLIC_VARIABLE = 25; a.PUBLIC_MEMBER_FUNCTION(1, 2);
