Object Literal Property Value Shorthand

Question

When creating JavaScript factory functions I was taught that the return syntax looks like the below:

function FF(constructorArg) {
   var _privateName = construc         


        

Answer 1

That's a shorthand syntax of defining object literal properties that was introduced by ECMAScript2015 (a.k.a. ES6). The only possible problem is environmental support. The environment should support this feature.

For supporting ES5-based environments you can use an ES6 transpiler and convert the code into ES5.

Answer 2

This is new es6 syntax. Only some browsers will support it unless you are compiling to es5. See the compatibility table: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer
