Explain data binding types.

Expert JavaScript
Quick Answer Data binding types: One-way (parent รขโ€ โ€™ child via props/inputs): data flows down, changes in parent update child. Two-way: {{model}} with ngModel in Angular, v-model in Vue รขโ‚ฌโ€ input changes update state, state changes update input. Event binding (child รขโ€ โ€™ parent): emit events up. One-way bindings are more predictable; two-way is convenient for forms.

Answer

Angular supports one-way and two-way binding using property binding, event binding, and ngModel. React prefers one-way binding through state with explicit updates. Proper binding ensures correct UI rendering.
