I'm trying to recreate the indexOf array method in JavaScript. For the life of me, I can't figure out why the following isn't working:
function indexOf(array, value) {
for (let i = 0; i < array.length; i++) {
if (array[i] === value) {
return i;
}
return -1;
}
}
For example:
indexOf([1,2,1,3], 2) // should return 1
Thanks in advance.
You just need to move the
return -1
outside of yourfor
loop.
