9,618 PointsIs is possible to use a function that returns a function to make your code more concise?
Here is a snippet of code from my app.js file that shows what I mean
handleChangeScore = (index) => {
return (change) => {
console.log(change);
};
}
render() {
return (
<div className="scoreboard">
<Header
title="Scoreboard"
totalPlayers={this.state.players.length}
/>
{/* Players list */}
{this.state.players.map((player, index) =>
<Player
name={player.name}
score={player.score}
id={player.id}
key={player.id.toString()}
changeScore={this.handleChangeScore(index)}
removePlayer={this.handleRemovePlayer}
/>
)}
</div>
);
}
