React question detail
Props
- Definition: Props (short for “properties”) are inputs to a component, provided by its parent component.
- Mutability: Props are read-only. A component cannot modify its own props; they are immutable from the component’s perspective.
- Scope: Props are used to pass data and event handlers down the component tree, enabling parent components to configure or communicate with their children.
- Usage: Props are commonly used to make components reusable and configurable. They allow the same component to be rendered with different data or behavior.
- Analogy: Think of props as arguments to a function, whereas state is like variables declared inside the function.
