Welcome back to our TypeScript series! In Part 2, we are moving beyond basic variables to master one of the most important structures in programming: Arrays. In JavaScript, arrays are flexible but can often lead to runtime errors if you accidentally mix data types. In this video, I’ll show you how TypeScript solves this by enforcing type safety. We will cover everything from simple type annotations to working with complex arrays of objects. What we are exploring today: Defining Arrays: How to use the square bracket [] syntax vs. the Generic Array syntax. Type Safety: Preventing mixed-type errors and ensuring your data remains consistent. Multi-dimensional Arrays: How to handle arrays within arrays (nested arrays). Hands-on Practice: We will write code together to see how TypeScript's IntelliSense helps you catch bugs before you even run your file. If you’re building production-ready applications, understanding how to strictly type your data structures is a non-negotiable skill. Let’s dive in and see how it works!
