A Beginner's Guide to TypeScript: Building Better JavaScript

🚀TypeScript is a programming language that builds upon JavaScript, allowing for easier and more powerful code development.

🧩TypeScript adds new features and advantages to JavaScript, making it a better and more reliable version of the language.

🔑One of the key features of TypeScript is the ability to add types, which enables early error detection and improved code quality.

📝TypeScript can catch logical errors and provide better error checking during development, avoiding runtime errors in JavaScript.

🛠️TypeScript can be used in various JavaScript projects, including browser-based applications, server-side applications, and frameworks like React and Node.js.
