What are props in React?

Props are inputs to components. They are single values or objects containing a set of values that are passed to components on creation using a naming convention similar to HTML-tag attributes. They are data passed down from a parent component to a child component.

The primary purpose of props in React is to provide following component functionality:

  1. Pass custom data to your component.
  2. Trigger state changes.
  3. Use via this.props.reactProp inside component's render() method.

For example, let us create an element with reactProp property:

<Element reactProp={'1'} />

This reactProp (or whatever you came up with) name then becomes a property attached to React's native props object which originally already exists on all components created using React library.

props.reactProp
