Can a component modify its own props?

Entry React
Quick Answer No. Props are read-only by design รขโ‚ฌโ€ a component receives them from its parent and must use them as-is. Modifying props would break the data flow and make components unpredictable. If a component needs to change data, it either calls a callback prop (to let the parent update state) or manages that data in its own state.

Answer

No. Props are immutable and controlled by the parent. Changing them breaks unidirectional data flow.
