How to create an array containing 1…N

Question

I\'m looking for any alternatives to the below for creating a JavaScript array containing 1 through to N where N is only known at runt

Answer 1

Just another ES6 version.

By making use of Array.from second optional argument:

Array.from(arrayLike[, mapFn[, thisArg]])

We can build the numbered array from the empty Array(10) positions:

Array.from(Array(10), (_, i) => i)

---

var arr = Array.from(Array(10), (_, i) => i);
document.write(arr);
