Tests:
Array.from
const elements = document.all; const arr = Array.from(elements);
Array.slice
const elements = document.all; const arr = Array.prototype.slice.call(elements, 0);
Array.push
const elements = document.all; const amount = elements.length; const arr = []; for (let i = 0; i < amount; i += 1) arr.push(elements[i]);
Array[index]
const elements = document.all; const amount = elements.length; const arr = Array(amount); for (let i = 0; i < amount; i += 1) arr[i] = elements[i];
Array spread
const elements = document.all; const arr = [...elements];
