Hmm it depends on which scenarios you want to support. Is there a minimum character count for repetition to remove? – Justus Romijn Dec 04 '18 at 13:21

Hi, welcome to SO. If you have written code for this that you can't get to work, then you have come to the right place. Just [edit] the question and add the relevant parts of your code into it. You need to show your own efforts, because Stack Overflow is not a write-my-code-for-me service. Also please see **[ask]** – Peter B Dec 04 '18 at 13:22

Is it always a sting like "wordword" or could it be more complex? – tifi90 Dec 04 '18 at 13:22

@Teun it's *not* a duplicate because you can't do 'Split by spaces' here (or any other separator). – Peter B Dec 04 '18 at 13:23

Here you go:
const str = 'pandorapandora'
const midIndex = Math.floor(str.length/2)
const firstHalf = str.slice(0,midIndex)
const secondHalf = str.slice(midIndex)
const dup = firstHalf == secondHalf ? firstHalf : str
console.log(dup)
