Angular - Template-Driven Forms
Why is two-way binding with [(ngModel)] considered less suitable for reactive forms compared to template-driven forms in Angular?
ATwo-way binding is slower in reactive forms
BReactive forms use explicit form controls and observables, not <code>ngModel</code>
CReactive forms do not support input elements
DTemplate-driven forms cannot use <code>ngModel</code>
Step-by-Step Solution

  2. Step 2: Compare with ngModel

    [(ngModel)] is designed for template-driven forms and is not recommended or supported in reactive forms.
  3. Final Answer:

    Reactive forms use explicit form controls and observables, not ngModel -> Option B
  4. Quick Check:

    Reactive forms avoid ngModel, use FormControl instead [OK]
Quick Trick: Reactive forms use FormControl, not [(ngModel)] [OK]
Common Mistakes:
MISTAKES
  • Thinking ngModel works well with reactive forms
