Reduce with filled array
arr.reduce((acc, x, index) => { acc[index] = x; return acc; }, new Array(arr.length));
Reduce with filled array with null
arr.reduce((acc, x, index) => { acc[index] = x; return acc; }, new Array(arr.length).fill(null));
Reduce with new Array
arr.reduce((acc, x, index) => { acc[index] = x; return acc; }, new Array());
Reduce with var
const a = new Array(arr.length); arr.reduce((acc, x, index) => { acc[index] = x; return acc; }, a);
