About TypeScript

TypeScript is a superset of JavaScript, developed by Microsoft, that introduces static types, interfaces, and more to enhance the JavaScript development experience. It compiles down to plain JavaScript, ensuring wide compatibility across browsers and environments.

Key Features

  • Static Typing for more reliable code
  • Advanced IDE support and IntelliSense
  • Supports latest JavaScript features (ESNext)
  • Scalable to large projects and teams

Basic Setup

To start using TypeScript, you need to install it via npm:

npm install -g typescript

Explanation: This installs the TypeScript compiler globally so you can use the tsc command in your terminal.

Key Takeaways

  • Superset of JavaScript: TypeScript adds static typing to JavaScript for more robust code.
  • Compilation Step: TypeScript code transpiles into readable JavaScript, ensuring compatibility.
  • Tooling and IDE Support: Editor features like IntelliSense and refactoring are greatly improved.
