Why are indexes repeating when value in array repeats?

When the random number as a value in the array repeats, so does the index. Here is a visual: https://imgur.com/a/ME4ItgE

The indexOf() method returns the position of the first occurrence of a specified value in a string.

myRandomList.indexOf(myRandomList[i])

looks for the first occurrence of value myRandomList[i]

It would be easier to just use i instead.
