Script Preparation code:
var numbers = Array(1000).fill(null).map((x, i) => i.toString());
Tests:
Reflect.set
numbers.reduce((acc, n) => Reflect.set(acc, n, n) && acc, {});
Object.assign
numbers.reduce((acc, n) => Object.assign(acc, { [n]: n }), {});
Direct assignment
numbers.reduce((acc, n) => { acc[n] = n; return acc }, {});
