Must use destructing props assignment Eslint 

const Header = props => (
  <header>
    <h1>{props.title}</h1>
    <span className="stats">{props.totalPlayers} </span>
  </header>
);

I'm getting an eslint warning on props.title & props.totalPlayers that says I should be using destructing. How would this syntax be achieved ?

What the error is saying is that you shouldn't be using dot notation to reference the keys inside of the props object.

You'll need to do something like this:

const Header = props => (
  const {title, totalPlayers} = props;    // <-- This is the destructuring piece. 
  <header>
    <h1>{title}</h1>
    <span className="stats">{totalPlayers} </span>
  </header>
);

Here's a good simple explainer of what exactly is going on: https://wesbos.com/destructuring-objects/
