So, is ES2015 or ES6 the new version of javascript. Is that mean that I should more focus on ES2015 than other javascript courses? Also, is ES2015 going to be more dominant and most widely used javascript in the future?

Treehouse Guest TeacherThew new syntax for functions doesn't replace the existing syntax. The new syntax, called arrow function, doesn't have a scope (inherits outer-scope's "this" keyword).
While you can continue to write in ES5, it would be good to learn these new features too.

4,514 Pointswhy is it to me that ES2015 looks bit more complicated than javascript. So like.....
This one is javascript
var braveNewWorld = function( world ) { console.log( "Welcome to" + world ); };
This one is ES2015
var braveNewWorld = ( world ) => { console.log( "Welcome to" + world ); };
I personally would be more confused by ES2015 more, because it uses => as function and I think it would be more easier to understand as a word. Rather than a symbol.
