Introduction to TypeScript

TypeScript is a statically typed superset of JavaScript developed by Microsoft. It adds optional type annotations, making code more predictable and easier to debug.

Why Use TypeScript?

• Type Safety: Catches errors during development instead of at runtime.
• Better Tooling: Provides autocompletion, navigation, and refactoring in editors.
• Scalability: Makes large codebases easier to manage.
• Modern JavaScript: Supports latest features with backwards compatibility.

Example

Here’s a simple TypeScript function:

function greet(name: string): string {
  return `Hello, ${name}`;
}

console.log(greet('Alice'));
// Output: Hello, Alice
