You need to take a deeper look into your code. Right now it will always return true, because you're storing a character at some index, and then checking from beginning again so you reach the same index again, and obviously it will return true when you compare the 2.
Make use of console.log to debug your code, avoid global variables, and take a closer look at the description. "aba" should return false.
