JS - Quick ones - Removing Duplicates
How do you remove duplicates from an array?
During ES5 era, you'd either have to de-duplicate using an object (using it like as hashmap), or sort the array and iterate over to remove duplicates in-place or use lodash uniq().
But with Set() and spread operator it has become as easy as:
const arrayWithoutDuplicates = [ ...new Set(originalArray) ];
How easy!
BTW, it also works for an array of objects. How cool is that?
