Welcome! Today, we're exploring the concept of queues in TypeScript, a fundamental data structure that processes elements in a first-in, first-out (FIFO) order, akin to a line at a food truck. We aim to learn how to implement, analyze, and manipulate queues in TypeScript, with a focus on type annotations to ensure robust code. Let's dive in!

Imagine you're in line for a roller coaster. The first person in line is always the first to ride. queues in programming follow this principle, making the queue concept relatively easy to grasp and powerful to use.

queues can be efficiently implemented in TypeScript using arrays with type annotations for added safety. Take a look at this simple Queue class:

This Queue class offers enqueue and dequeue methods to manage the 's state with type safety.
