React - How to access props without using constructor

If you want to use this.props in the constructor, you need to pass props to super. Otherwise, it doesn't matter because React sets .props on the instance from the outside immediately after calling the constructor.

So just simply remove constructor() if useless

you can access props without constructor in a class using "this", like this:

class XXXXXX extends React.Component {
   render() {
       return (
          <div>{this.props.value}</div>
       )
   }
}
