=== does a strict comparison, which includes type. .value always returns a string, but your array has integers in it. So while 1 == '1'; //true, 1 === '1'; //falsehmm
i dont get it
i cant use value with ===?
you can, but you'd have to compare against other strings, or convert your string into an integer
or just use
==, that's probably fine in this case anywayi use == not work
ohh
it work
lol i was not lucky after 30 time attembd it alwse get another number
tnx for help == work
https://javascript.info/comparison here's more info on comparisons and strict comparisons
and on data types https://javascript.info/types
Tnx
btw fyi,
document.getElementById('getter').valueAsNumber would return a numberI didn't even know valueAsNumber is even a thing lol
