Can you explain the difference between props and state in React?
Sure! In React, props are used to pass data from one component to another, while state is used to manage data within a component.
Can you give me an example of how to use props?
Absolutely! If you have a Greeting
component, you can pass a name
prop like this: <Greeting name='Alice' />
, and then access it in the component using this.props.name
.
And how about state? How do I set it?
You can set state using the setState
method. For example, this.setState({ count: this.state.count + 1 })
updates the count
state.
So, can props change over time?
No, props are immutable. They can only be changed by the parent component that owns them, while state can change over time within the component.
