Describe the benefits of using TypeScript with React.

Q: Describe the benefits of using TypeScript with React.

**Core concept (TL;DR).** TypeScript adds **static typing** to React: you type props, state, hooks, events, and context, so mistakes (wrong prop, missing field, bad event handler) are caught at **compile time** instead of crashing at runtime. You also get far better **autocomplete**, **refactoring**, and self-documenting components. Catch prop/state mistakes before runtime plain JS <text x="135" y="8

Read the code

A typed component + hook (TSX)

import { useState } from "react";

type User = { id: number; name: string };
type Props = { user: User; onSelect?: (id: number) => void };

// props are checked at compile time; missing/extra props won't compile
export default function UserCard({ user, onSelect }: Props) {
  const [open, setOpen] = useState<boolean>(false);
  return (
    <div style={{ padding: 24, fontFamily: "system-ui" }}>
      <button onClick={() => { setOpen(o => !o); onSelect?.(user.id); }}>
        {user.name}
      </button>
      {open && <p>id: {user.id}</p>}
    </div>
  );
}
