Benchmark: Convert querySelectorAll to array + push

Script Preparation code:

maind = document.createElement('div');
for (let i = 0; i < 10000; i++) {
    let d = document.createElement('div');
    maind.appendChild(d);
}
document.body.appendChild(maind);

Tests:

Array.prototype.slice.call
Array.prototype.slice.call( maind.querySelectorAll('div') );
[].slice.call
[].slice.call( maind.querySelectorAll('div') );
...
[...maind.querySelectorAll('div')]
push
a=[]; for(let i=0; i<10000; i++) { a.push(maind[i]); }
