expected assignment or function call no-unused-expressions ReactJS

Question

This is my code:

class Game extends Component 
{
  constructor() 
  {
    super()
    this.state = {
      speed: 0
    }
    //firebaseInit()
  }
  render()
  {
    return 
    (
      <div>
        <h1>The Score is {this.state.speed};</h1>
      </div>
    )
  }
}

export default Game;

I am getting this error when I execute the above code:

Expected an assignment or function call and instead saw an expression  no-unused-expressions

What is the problem with the code? 

Answer 1

The problem is that you have put the bracket of return on the next line. This makes the interpreter thinks that you return undefined and don't check your next line. To solve this just put your opened bracket on the same line as the return.

I hope this helps you.
