javascript - JavaScript 中的对象操作数组

Question

我在对象内有一个空数组，如下所示，

const account = {
name: "David Reallycool",
expenses: []

}

我需要创建一个函数将费用添加到空数组中，我需要的结果是，

const account = {
name: "David Reallycool",
expenses: [
    {
        descrition: "Rent",
        amount: 1000
    },
    {
        description: "Coffee",
        amount: 2.50
    }
]

我该如何操纵它？

Answer 1

const addExpense = (expense) => {
  account.expenses.push(expense)
}
// use like this
addExpense({ description: 'Rent', amount: 1000 })
addExpense({ description: 'Coffee', amount: 2.5 })
