javascript - 有没有办法重构具有相似名称的变量？

Question

const { finalScore1, finalScore2, finalScore3, finalScore4, finalScore5, finalScore6,
        finalScore7, finalScore8, finalScore9, finalScore10, finalScore11, finalScore12,
        finalScore13, finalScore14, finalScore15, finalScore16, finalScore17, finalScore18
 } = this.state

似乎是一种非常不干燥的变量声明方式。有没有办法做类似 finalscore${x} 的事情并使用循环？

Answer 1

您应该保留一个数组，而不是保留 18 个键作为 finalScore${x}

state = {
   finalScores: []
}

然后您就可以访问this.state.finalScores[x]。您还可以循环 FinalScores 状态数组并获取值
