A clearer explanation of the arrow function

Check this video for a clearer more straight forward explanation of the arrow function without the mention of promises or extra code bloat.

Nice video so far, looking forward to looking at it further.

But I've liked the way the new ES6 course has explained some of the concepts.

My only question might sound a bit obvious but I don't think the course explained this yet, but how do we get started using the new features...

just as standard JS file as usual and a modern browser?

Jonathan Grieve, Depends on what browser you use. Newer versions of browsers will be running ES6. Node.js has about 99% of ES6 support as of this writing. In order to ensure backwards compatibility Devs should use the Babel compiler to turn ES6 code into ES5 code. Then, over time when most browsers that support ES5 are depreciated, one can use the ES6 code directly without worry.

Hope this helps.
