Enable JSX in tsconfig.json

WHEN Using JSX syntax in TypeScript files

Enable JSX in tsconfig.json
// tsconfig.json
{
  "compilerOptions": {
    "jsx": "react-jsx"  // or "react", "preserve", etc.
  }
}

Why this works

The '--jsx' option tells TypeScript how to transform JSX; choose 'react-jsx' for React 17+ or 'react' for older versions.
