As per Wikipedia: "JavaScript is classified as a prototype-based scripting language with dynamic typing and first-class functions. This mix of features makes it a multi-paradigm language, supporting object-oriented,[6] imperative, and functional[1][7] programming styles." But we still never explore the object orientation side of it, to start with.. we can create Class & Modules to divide the program in small chucks oflogic. This example shows you how to create a class in JavaScript.
As per the above code, we have defined a class which is actually a function since JScript don't have class keyword and a constructor(will be same as the class name). "this" refers to the current object in memory and the variable1 is prototyped to it.
