What means => used in this way in Javascript syntax?

Question

I searched something on SO and run into this, which is a way to retrive a file from your local computer and use it in browser, with AngularJS.

this.http.get(<path_to_your_json_file>)
 .success((data) => console.log(data));

I wonder what this JavaScript syntax could mean:

(data) => console.log(data)

I don't know if is something AngularJS specific, but I mostly doubt so. Do you know more interesting tweaks which are no so common in daily use of JavaScript?

It's called an arrow function. They are very common in ES6. – 4castle Nov 20 '16 at 21:43 — 4castle, Nov 20 '16 at 21:43

It can't be used in internet explorer? – Iulian Barbu Nov 20 '16 at 22:07 — Iulian Barbu, Nov 20 '16 at 22:07
Internet Explorer is too old to support it. – Quentin Nov 20 '16 at 22:50 — Quentin, Nov 20 '16 at 22:50

This is an arrow function: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions.

Arrow functions were introduced into JavaScript with ES2015.

Writing (data) => console.log(data) is equivalent to writing function (data) { console.log(data); }.
