Let’s get started,

When you want to access this.props in constructor() then you should pass props to super() method.

Using super(props):

class MyComponent extends React.Component {
  constructor(props) {
    super(props)
    console.log(this.props) // { name: 'John', ... }
  }
}

Using super():

class MyComponent extends React.Component {
  constructor(props) {
    super()
    console.log(this.props) // undefined
  }
}
