What are typescript types? In detail?..

Answer / Dinesh Baboo

TypeScript is a superset of JavaScript that adds static typing, classes, interfaces, and other features to make JavaScript more robust and scalable. TypeScript types can be divided into three main categories:

1. Basic Types: `number`, `string`, `boolean`, `any`, `void`, `null`, `undefined`, and `never`.

2. Complex Types: `Array` (with generic support), `Tuple` (a fixed-length array with typed elements), `Enum` (custom named values for a set of related constants), `Interfaces` (defining the structure of an object), `Classes` (blueprint for creating objects), and `Type Aliases` (giving custom names to types).

3. Type Annotations: Adding type information to variables, function parameters, and return values using syntax like `let myVar: number = 123;`. This enables better autocompletion, type checking, and code navigation in integrated development environments.
