Quick answers about this topic hub.
Should I use TypeScript instead of JavaScript?▾
For anything beyond a small script, TypeScript's static types catch bugs early, improve autocomplete, and make refactoring safer. The main cost is a compile step and a learning curve — usually well worth it for teams and growing projects.
What are generics in TypeScript?▾
Generics let you write reusable code that works over many types while preserving type safety — for example, a function that returns the same type it receives. They're key to typing collections, utilities, and APIs precisely.
How do I add TypeScript to an existing project?▾
Introduce it gradually: add a tsconfig, rename files to .ts one area at a time, and use loose settings before tightening them. TypeScript is designed to be adopted incrementally alongside existing JavaScript.
