element.children vs element.querySelectorAll vs element.querySelectorAll(:scope) (version: 0)
Really basic test comparing accessing children via parentElement.children vs via querySelectorAll vs scoped querySelectorAll.
Not a great test for the use case, but people who are less lazy than me can fork it and make it do thing good.
Comparing performance of:children vs querySelectorAll vs querySelectorAll(:scope) vs children.forEach vs querySelectorAll().forEach vs querySelectorAll(:scope).forEach
