Confirm the Ending for string using split array

Tell us what’s happening:
test error : 2) confirmEnding(“Congratulation”, “on”)` should return true.
any help please?
if i uses reduceRight is good idea?

Your code so far

function confirmEnding(str, target) {
let arr = str.split("");
return arr[arr.length-1]==target ;

confirmEnding("Bastian", "n");

Challenge: Confirm the Ending

Link to the challenge:

As you can see, you have a precise value hard-coded, -1.
But what if the string to confirm is longer, like in the test that’s failing?

With your code so far:

confirmEnding("Bob", "b") // true
confirmEnding("Bob", "ob") // false

Hope this helps :sparkles:
