if you want better intellisense to figure out what's going on, make sure you enable strictNullChecks: true and alwaysStrict: true

That will enhance your TSX experience

{
    "compilerOptions": {
        "target": "es5",
        "module": "esnext",
        "lib": ["ESNext", "DOM", "DOM.Iterable"],
        "declaration": true,
        "strict": true,
        "noImplicitAny": true,
        "strictNullChecks": true,
        "noImplicitThis": true,
        "alwaysStrict": true,
        "moduleResolution": "node",
        "noUnusedLocals": false,
        "noUnusedParameters": false,
        "jsx": "preserve",
