() => { return ... } is yet another anonymous arrow function, except this time, instead of invoking the function in place, we store in a variable named a so that we can invoke it later a() calls the previously stored function, which in turn calls (b) => alert(b) with the argum...

Arrow functions evaluate the right-side of the => differently if a { exists. { Begins a block statement and when using a block on the right-side of an Arrow Function, a return is required. If a block isn't used on the right-side of an Arrow Function, then the evalua...
This answer is equivalent to some of the existing answers, but ECMAScript 6 arrow functions provide a much more compact syntax that allows us to define an inline sort function without sacrificing readability: numArray = numArray.sort((a, b) => a - b); It is supported in ...
