How to Solve Two Sum with Hash Table in JavaScript | LeetCode Challenge

The LeetCode Challenge "Two Sum" can be solved using a Hash Table in JavaScript. This problem involves finding two numbers in an array that add up to a specific target value. The solution involves using a hash table to store the values in the array as keys and their indices as values. Then, for each element in the array, the solution checks if the target minus the element is present in the hash table, and if it is, the indices of the two elements are returned as the solution to the problem. This approach has a time complexity of O(n) and is a widely used method for solving the Two Sum problem.
