Benchmark: array clone variants

Script Preparation code:

const SIZE = 1_000_000;
const original = Array.from({length: SIZE}, (_, i) => i);

Tests:

spread
const copy = [...original];
slice
const copy = original.slice();
Array.from
const copy = Array.from(original);
map
const copy = original.map((x) => x);
for
const copy = []; for (let i = 0; i < original.length; i++) { copy[i] = original[i]; }
while
const copy = []; let i = 0; while (i < original.length) { copy[i] = original[i]; i++; }
structuredClone
const copy = structuredClone(original);
