In this article, we’ll explore the hash table data structure, which provides fast data access using keys. We'll build our own hash table step-by-step in JavaScript, covering how it stores data, handles collisions, and retrieves values.

The Two Sum problem is a popular coding challenge that involves finding pairs of numbers in an array that add up to a specific sum. This is a great problem to practice your problem-solving skills and reinforce your understanding of hash tables for improving time complexity.

In this post, we'll break down a common algorithm question you might see in coding interviews: the Harmless Ransom Note. It’s a great example to understand how to manipulate strings and use objects as hash tables for performance improvements. Plus, it’s relatively straightforward but offers a solid practice in understanding time complexity.
