Object doesn't support property or method 'fill'

Question

I cannot find same problem online. IE 11 gives error \"Object doesn\'t support property or method fill\".

var arr = new Array(5);
arr.fill(false         


        

Answer 1

You could use Array.apply for getting an array with the wanted length and then map the value to it.

var a = Array.apply(null, { length: 5 }).map(function () { return false; });
console.log(a);
