javascript - 如何在 Javascript 中将数组转换为对象？

Question

我有以下数组:

const x = [
    {event: "oninput", action: ""},
    {event: "onfocus", action: ""}
]

以下是所需的输出:

// event: action
{
    oninput: "",
    onfocus: ""
}

我尝试了以下并没有真正起作用:

const x = [
    {event: "oninput", action: ""},
    {event: "onfocus", action: ""}
]

console.log({...x.map(y => {return {[y.event]: y.action}})})

你可以使用 Object.assign并映射对象。这会收集所有对象并将其分配给单个对象。

const x = [
    { event: "oninput", action: "" },
    { event: "onfocus", action: "" }
];

console.log(Object.assign(...x.map(({ event, action }) => ({ [event]: action }))));
