Solving a Common Interview Question: the Two Sum Algorithm in JavaScript

The Two Sum Problem is a popular algorithm challenge where the goal is to find indices of two numbers in an array that add up to a target value. Two solutions are discussed: the brute force method, which checks all pairs and has a time complexity of O(n^2), and a more efficient approach using a hash map, which brings the time complexity down to O(n). The hash map method stores indices of elements for quick lookups, making it significantly faster for large arrays.
