TYPESCRIPT
TypeScript is a superset of JavaScript that adds static typing to the language. It enhances the development experience by catching errors early in the development process and providing better tooling for large-scale applications.
Getting Started
To start using TypeScript, follow these steps:
1. Installation
- Install TypeScript globally using npm (Node Package Manager).
npm install -g typescript
2. Create a TypeScript file
- Create a file with a .ts extension, for example, app.ts.
3. Write TypeScript Code
- Write your TypeScript code using TypeScript features such as static typing, interfaces, and classes.
4. Compile TypeScript to JavaScript
- Compile your TypeScript code to JavaScript using the TypeScript compiler (tsc).
tsc app.ts
5. Run the JavaScript
- Run your JavaScript code in the Node.js environment or a browser.
