DOM get attributes of children vs JS Array READ performance v3
Results: Reading the DOM with nextElementSibling + getAttribute is less than 5% slower than an JS array list. textContent is slightly faster than a JS array list, and nodeValue is 3X faster. Listing a JS array in a for i-- loop backwards yield ~2X performance |

Fastest way to list children: childNodes vs children vs firstChild/nextSibling vs firstElementChild/nextElementSibling v2 fixed
Result: firstElementChild is the fastest yielding 3-4X performance. With lastElementChild close (margin of error) 2nd. Other observations: doing for loop i-- with children shows ~150% higher performance vs i++. And unloading it into a variable prior yields another ~200% boost |
