Optional chaining lets you safely access deeply nested properties without throwing an error if an intermediate value is null or undefined.
TypeScript
const user = { name: "Alice", address: null,
}; const city = user.address?.city; // undefined, no error
const street = user.address?.street ?? "unknown";
console.log(city, street); // undefined "unknown"
