Remove Duplicate Values From an Array in JavaScript Using ES6

We can easily get the distinct values in our JavaScript array by using the spread operator.

const arr = [1,1,4,5,5,37,57,28,67,67];
console.warn(arr); // [1,1,4,5,5,37,57,28,67,67]

//With Spread operator
const newArr = [...(new Set(arr)];
console.warn(newArr); //[1,  4,  5, 37, 57, 28, 67]

The spread operator makes it for us to iterate over an array and return distinct values.
