How to Merge Two Arrays Without Duplicates in JavaScript?
I need to merge two arrays while removing duplicates. Here’s what I’ve come up with using Set:
const arr1 = [1, 2, 3];
const arr2 = [3, 4, 5];
const merged = [...new Set([...arr1, ...arr2])];
console.log(merged); // [1, 2, 3, 4, 5]

Your approach using Set to merge the two arrays and remove duplicates is perfect! The Set object inherently ensures that only unique values are stored, and the spread operator (...) makes it simple to combine arrays.
Here's a quick breakdown of what you're doing:
[...arr1, ...arr2] merges the two arrays. new Set() removes any duplicates. Finally, the spread operator [...new Set(...)] converts the Set back into an array. Your solution is clean and efficient for this task. Well done!
