4,010 PointsremovePlayer function not working
My code isn't producing the intended result, the players names are not being removed from the array when I click the "x" next to their name.
const Player = (props) => {
return (
<div className='player'>
<span className='player-name'>
<button className="remove-player" onClick={ () => props.removePlayer(props.id) }>✖</button>
{props.name}
</span>
<Counter />
</div>
)
}
class App extends React.Component {
state = {
players: [
{
name: "Guil",
id: 1
},
{
name: "Treasure",
id: 2
},
{
name: "Ashley",
id: 3
},
{
name: "James",
id: 4
}
]
};
handleRemovePlayer = (id) => {
this.setState( prevState => {
return {
player: prevState.players.filter( p => p.id !== id )
};
});
}
render () {
return (
<div className='scoreboard'>
<Header title="Scoreboard" totalPlayers={this.state.players.length} />
{/* player list */}
{this.state.players.map(player =>
<Player
name={player.name}
id={player.id}
key={player.id.toString()}
removePlayer={this.handleRemovePlayer}
/>
)}
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById('root'));

4,010 PointsI fixed it. On this line, I typed "player" instead of "players"
The code is working normally.
return {
player: prevState.players.filter( p => p.id !== id )
};
