React [closed]中的Cleaner语法

Question

在React / js中，有没有一种以更简洁的方式声明此数组的方法？

numbers_of_calls = []
marital_statuses = []
plan_involvements = []

还有这个：

state = {

        formData: [[], [], []]

    }

处于状态的formData将由这3个数组填充

Answer 1

为什么不：

state = {
    numbers_of_calls = [];
    marital_statuses = [];
    plan_involvements = [];
};

然后，当您准备使用它时，您可以做：

const formData = [
    this.state.numbers_of_calls,
    this.state.marital_statuses,
    this.state.plan_involvements
]
