attribute finding: querySelectorAll vs evaluate
trying to see how to best emulate $x(), and how that compares to querySelectorAll (in a case where there is an equivalent pattern) unfortunately can't test against $x(), but I reckon it would've been way faster than the methods employed here to construct something array-like from evaluate() to mimic it :( |
