What is the difference between props and data in Vue.js?

What is the difference between props and data in Vue.js?

In Vue.js, 'data' is used for local state management within a component, while 'props' are used to pass data from a parent component to a child component.

Can you give me an example of how to use props?

Sure! If you have a parent component that holds a user's name, you can pass it to a child component like this: <ChildComponent :name='userName' />.

What happens if I try to modify props in the child component?

Props are read-only in the child component. If you try to modify them, Vue will warn you, as it can lead to unexpected behavior.

When should I use props instead of data?

Use props when you need to pass data from a parent to a child component. Use data for internal state management within a component.
