Remove duplicate words in array elements

Question

I have a small problem with replace words in array. Ok, this my array:

var words = ['Category One Category One Clothes', 'Category One Category One Jackets'];

I want final result like this:

var result = ['Category One Clothes', 'Category One Jackets'];

Try with this method, but not working Removing duplicate strings using javascript

Answer 1

For the given input, this should work.

words.map(w => w.replace(/([\w\s]+)\1+/, '$1'))

var words = ['Category One Category One Clothes', 'Category One Category One Jackets'];
var result = words.map(w => w.replace(/([\w\s]+)\1+/, '$1'));
console.log(result);

The regex ([\w\s]+) will match the words/spaces and \1+ will match the same word again.
