Hi everyone! I am curious…
My code works (see base of post for it), but it has raised a question.
Would it be better to use the .toLowerCase() method on the two strings before the for loop - so the method only runs 1 time for each variable instead of multiple times within the loop (possibly making load times longer)?
So, if I instead did:
var string1 = arr[0].toLowerCase();
var string2 = arr[1].toLowerCase();
and used the var names in the for loop instead of arr[0].toLowerCase() and arr[1].toLowerCase() , would that be better? Or no difference?
This is my code::
function mutation(arr) {
for (let i=0; i<arr[1].length; i++) {
var checker = arr[0].toLowerCase().indexOf(arr[1].toLowerCase()[i]);
if (checker < 0) {
return false;
}
}
//loop finished without false (no -1 from the indexOf search) -> all letters were matched.
return true;
}
mutation(["hello", "hey"]);
Thanks for your help
