Removing duplicate array values and then storing them [react]

Question

I\'m trying to strip the duplicate array values from my current array. And I\'d like to store the fresh list (list without duplicates) into a new variable.

var          


        

Answer 1

you forgot to use return statement in the filter call

const namesArr = duplicatesArray.filter(function(elem, pos) {
    return duplicatesArray.indexOf(elem) == pos;
});
