switch (e.target.value) {
    case "nickname":
setPlayerCards(players.filter(player)=>{
 return player.nickname !== null
    
  
}))
  }

I don’t understand why there are so many parentheses, isn’t it possible to come up with something to prevent this nonsense from happening?

why doesn’t this code work?

Of course, there’s no way to figure it out, but how to write it correctly?

Your filter callback function syntax is not correct. The callback should be inside the parentheses with the parameter.

implicitly return player.nickname

This means no return keyword and no function body block {}.


[1, 2, 3, 4].filter((num) => num % 2 === 0) // [2, 4]
