Why is return required in this block of code?

handleAddPlayer = (name) => { this.setState( prevState => { return { players: [ ...prevState.players, { name, score: 0, id: this.prevPlayerId += 1 } ] } }); }

Hi Norman,

If you want to implicitly return an object literal you need to wrap it in parentheses. For example,

var func = (name) => ({ myName: name })

func("Tim") // { myName: "Tim" }

In your code above, the outer braces are the start of the function's code block. Without a return statement it doesn't know what you want to return.
