TypeScript for JavaScript Developers: A Complete Guide

TypeScript adds static typing to JavaScript, helping catch errors at compile time rather than runtime. For JavaScript developers, TypeScript offers a gentle learning curve while providing powerful features like interfaces, generics, and type inference. Start by adding types to function parameters and return values, then gradually adopt more advanced features. TypeScript integrates seamlessly with popular frameworks like React, Node.js, and Next.js. The benefits include better IDE support with autocomplete, easier refactoring, and self-documenting code that improves team collaboration.
