What are props in React? in REACT

Practice



props

Props are the input data for components. They are individual values or objects containing a set of values that are passed to components on creation, using a naming convention similar to HTML tag attributes. This is data passed from a parent component to a child component.

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

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

For example, let's create an element with a

reactProp
property: 
<Element reactProp={'1'} />
 

This

reactProp
(or whatever name you come up with) becomes a property attached to React's own props object, which already exists natively on all components created using the React library. 
props.reactProp
