differences
| state | props |
|---|---|
| Internal data, owned by component | External data, owned by parent component |
| Component "memory" | Similar to function parameters |
| Can be updated by the component itself | Read-only |
| Updating state cuases component to re-render | Receiving new props cuases component to re-render. Usually when the parent's state has been updated |
| Used to make components interactive | Used by parent to configure child component("settings") |
