TypeScript is a superset of JavaScript that adds static typing and powerful tooling.
For freelancers, it means fewer bugs, cleaner code, and happier clients.
With TypeScript, you get:
type User = {
id: number;
name: string;
email: string;
};
async function getUser(id: number): Promise<User> {
const res = await fetch(`/api/users/${id}`);
return res.json();
}
getUser(1).then(user => console.log(user.email));
