Unlock the power of **Union Types**, **Type Aliases**, and **Enums** in TypeScript to write cleaner, more flexible code. With **Union Types**, you can let variables hold multiple types, making your code more versatile. **Type Aliases** make complex types easier to read and reuse, while **Enums** help you manage related constants in a more organized way. These features give you the tools to build robust and maintainable applications.

Let us consider a previous example: const car: { brand: string; year: number } = { brand: "Tata", year: 2025 }; That works fine, but imagine you have lots of objects with the same shape. Typing { brand: string; year: number } again and again is messy. 👉 This is where interfaces come in.

TypeScript: Variables, Types & Functions

TypeScript is a superset of JavaScript that adds static typing to the language. This means you can define the type of a variable, function parameter, or object property, allowing the compiler to catch type-related errors before your code runs. This leads to more robust and maintainable code.
