Typed Reactive Forms giải quyết vấn đề gì?

Typed Forms giúp FormControl, FormGroup và valueChanges mang đúng TypeScript type, giảm lỗi truy cập field sai hoặc submit payload sai shape.

Ví dụ:

const form = new FormGroup({
  email: new FormControl("", { nonNullable: true, validators: [Validators.email] }),
})

const email: string = form.controls.email.value

Trong app lớn, typed forms làm refactor an toàn hơn vì compiler phát hiện form contract bị lệch.

Typed Forms make FormControl, FormGroup and valueChanges carry correct TypeScript types, reducing wrong field access or wrong submit payload shape.

Example:

const form = new FormGroup({
  email: new FormControl("", { nonNullable: true, validators: [Validators.email] }),
})

const email: string = form.controls.email.value

In large apps, typed forms make refactoring safer because the compiler catches form contract mismatches.
