Script Preparation code:

var arr = Array(10_000).fill(0)

Tests:

reduce with new array
arr.reduce((acc, x) => [...acc, x, x], [])
reduce with array mutation
arr.reduce((acc, x) => { acc.push(x); return acc; }, [])
flatMap
arr.flatMap(x => [x, x])
for
const newArray = []; for (let i = 0; arr.length > i; i++) { newArray.push(arr[i]); }
for-of
const newArray = []; for (let x of arr) { newArray.push(x); }
map
arr.map(x => x);
forEach
const newArray = []; arr.forEach(x => newArray.push(x));
values (iterates over for-of)
const newArray = []; for (let x of arr.values()) { newArray.push(x); }
