I have this JavaScript code

const numberWithCommas = (x) => { return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".");}

This works fine in Firefox and Chrome, however IE gives me an syntax error pointing at => in my code.

Is there a way to use ES6 arrow syntax in IE?

IE Does not Support ES6 – Luis felipe De jesus Munoz Mar 23 '18 at 12:09
Could you help me to transform this code to the javascript regular one? – Gabriel747 Mar 23 '18 at 12:11

*Is there a way to use ES6 arrow syntax in IE?* you can use a pre-compiler like [Babel](https://babeljs.io/). Though this wil just turn the arrow function into a standard function call and a `var _this = this` object, which is basically the same thing – Liam Mar 23 '18 at 12:11

Your not using scope so there is no reason to use an arrow function here, so you can re-write it simply: `var numberWithCommas = function(x) {....}` – Liam Mar 23 '18 at 12:13
Just change `(x) => ` to `function(x)` – Luis felipe De jesus Munoz Mar 23 '18 at 12:13
Since I'm not good at javascript, and this bunch of code need to be fixed urgently, could you assist me with the code mentioned upper? – Gabriel747 Mar 23 '18 at 12:14
@Liam Thanks a lot, works perfect. Great assist :) – Gabriel747 Mar 23 '18 at 12:15

The [babel website](https://babeljs.io/) will do this for you too. type your code into the textbox – Liam Mar 23 '18 at 12:16
