Tell us what’s happening:
can someone help me identify why my for loop is only pushing one of the values from the array? I’m trying to create a new array with only lowercase values. Thank you!
Your code so far
function mutation(arr) {
// var lowercase = String(arr).toLowerCase();
for (let i = 0; i < arr.length; i++) {
var lowercase = []
lowercase.push(arr[i].toLowerCase());
}
console.log(lowercase)
let result = lowercase[0].indexOf(lowercase[1])
if (result > 0) {
return true
} else {
return false
}
return arr;
}
mutation(["hello", "hey"]);
