# Getting Started with TypeScript TypeScript is a statically typed superset of JavaScript that compiles to plain JavaScript. It offers optional static typing, classes, and interfaces. Let's explore the basics. ## Basic Types TypeScript offers a variety of basic types, such as `number`, `string`, `boolean`, `array`, and `tuple`. ```typescript let isDone: boolean = false; let decimal: number = 6; let color: string = 'blue'; let list: number[] = [1, 2, 3]; let x: [string, number] = ['hello', 10]; ``` ## Interfaces Interfaces define the structure that an object should follow. ```typescript interface Person { firstName: string; lastName: string; } function greeter(person: Person) { return `Hello, ${person.firstName} ${person.lastName}`; } let user = { firstName: 'John', lastName: 'Doe' }; console.log(greeter(user)); ``` ## Getting Started To get started with TypeScript, install it globally via npm: ```bash npm install -g typescript ``` Create a TypeScript file (`example.ts`) and compile it: ```bash tsc example.ts ``` This will generate a corresponding JavaScript file (`example.js`) that you can run with Node.js.

Long Description

TypeScript is a powerful tool that enables developers to write safer and more robust code by adding static types to JavaScript. In this blog, we'll cover the basics of TypeScript, including types, interfaces, and how to get started.
