What to do if Array.from() is not supported for IE?

Question

I am using Array.from() function which is supported in all browsers, except IE:

function range(start, end) {
    return Array.from(Array(end - start + 1), (_, i) => i + start);
}

Instead of Array.from() what function can I use to make my code compatible with IE?

Answer 1

Use a Polyfill.

if (!Array.from) {
    Array.from = (function () {
        // The code gose here...
    })();
}

As described in Mozilla please refer below link,

Answer 2

Use a simple for loop

function range(start, end) {
    var array = [];
    for(i = start; i<=end; i++) {
      array.push(i);
    }
    return array;
}
console.log(range(3, 5));

Answer 3

The problem is not Array.from it is the arrow function, try

function range(start, end) {
  return Array.from(Array(end - start + 1), function (_, i) { return i + start; });
}
