For more quicker way use Set() as for ex: Array.from(new Set(myArray))

[zeyadmoamen]

solution in one line
[...new Set(ids)]

[rounakbhattacherjee]

The explanation is not clear enough, what is the indexof method doing when it finds a duplicate,
Indexof returns -1 when it finds a duplicate element in the array when then compared to the index doesn't match the value hence it's not filtered to the new array..


I feel there is a more easier way here, just simply spread the array inside a set, when we need the unique values...only when duplicates needs to be addressed this method is more useful...
Anyways good work keep it up mate
