JS Interview Q52: Remove Duplicates ❌
Want to remove duplicate values from an array in the cleanest way possible?
In this short, I break down how JavaScript's Set object can help you instantly get unique elements from an array. Using [...new Set(arr)], we convert a Set back into an array while automatically filtering out duplicates — no loops, no fuss.
Using the array [1, 2, 2, 3, 4, 4, 5] as an example, I show how we get back [1, 2, 3, 4, 5] with a one-liner. This is a super handy trick in interviews and real-world coding — especially when you're working with large datasets or cleaning up user input.
If you're preparing for a JavaScript interview, or want to level up your array methods game, this is a must-know technique!
