But they're not fully interchangeable, for example I can exit a function at any
point with a return, but can I exit a block at any point with a break or
something? Also a function returns a value, does a block evaluate to something?
In any case, I would really like to know which parenthesis or curly braces can
I leave out in an immediately invocated arrow function expression, for example
this:
var x= (=>{
//...
})();
Is it correct ES6? Is there anything else that I could rmv in that IIAFE?
Thank you!
