This trick is actually part of the syntax for: Classes Similarly, classNames will then receive these as separate arguments, not as a single array. So you can pass any number of arguments to c, and they’ll end up in the args array. Why? Have an example: ES6 function initialize(`)

But given the breadth of the changes, how is a forward-thinking developer to know where to start? What is worth practicing now, and what is best left for a rainy day? And with all of the benefits that the new syntax and built-ins bring, it damn well should. Just want examples of ES6 in use? I’ve put four ES6 projects on Github.ĮS6 has been getting a lot of press lately.
