Passing state down as props in React

I have my main component called App.

App pulls in the Table component like so:

<Table
  players={players}
/>

players is initially defined in the App component's state as an empty array but inside my Table component I do this:

console.log(this.props.players, 'players');

Why would I get undefined?

I also have this inside my App component:

render() {
   const { players, matches } = this.state;
Solution

  • Regarding my comment in your question you need to do something like this:

    <Table
  players={this.state.players}
/>

    This way you are getting players from inside your state. Without "this.state" you will receive and undefined error
