How do I use default props in React?

How do I use default props in React?

You can use default props in React by defining them on your component. For example, you can set default values for props like this:

MyComponent.defaultProps = {
  myProp: 'default value',
};

Can I override default props when I pass props to the component?

Yes, if you pass a prop to the component, it will override the default prop value. For example:

<MyComponent myProp='new value' />

In this case, myProp will be 'new value' instead of 'default value'.

What happens if I don't provide a prop and there's no default value?

If you don't provide a prop and there's no default value set, the prop will be undefined in your component.

Are there any best practices for using default props?

Yes, it's a good practice to use default props for optional props to ensure your component behaves predictably. Also, consider using PropTypes to validate your props.
