Challenge: Check if Arrays are Disjoint

Explore how to determine whether two arrays are disjoint, meaning they share no elements. Learn to implement this using hash tables to efficiently handle array comparisons and deepen your understanding of hashing in JavaScript.

We'll cover the following...

Statement

Given two arrays, determine whether or not they are disjoint.

Note: Arrays are disjoint if they have no common element between them.

Constraints:

  • 11 \leq arr1.length,
