Javascript使用唯一键将数组推送到数组

我有一个数组如下的对象：

const result = {
    key1: [],
    key2: [],
    key3: [],
    key4: []
};

result.key1.push({key11: []})
result.key1.push({key12: []})
result.key1.push({key13: []})

{
    key1: [
        key11: [],
        key12: [],
        key13: []
    ],
    key2: [],
    key3: [],
    key4: []
}

我想按下其中一个“键”，比如：

const result = {
    key1: [],
    key2: [],
    key3: [],
    key4: []
};

result.key1.push({key11: []})
result.key1.push({key12: []})
result.key1.push({key13: []})

{
    key1: [
        key11: [],
        key12: [],
        key13: []
    ],
    key2: [],
    key3: [],
    key4: []
}

但我需要这样的结果：

const result = {
    key1: [],
    key2: [],
    key3: [],
    key4: []
};

result.key1.push({key11: []})
result.key1.push({key12: []})
result.key1.push({key13: []})

{
    key1: [
        key11: [],
        key12: [],
        key13: []
    ],
    key2: [],
    key3: [],
    key4: []
}

我尝试了几乎所有的方法。我错过了什么吗？

你把对象和数组搞混了。数组按从0到长度-1的顺序排列项，而对象具有命名键。看起来您正在寻找命名键，因此需要创建一个对象

const result = {
    key1: {},
    key2: {},
    key3: {},
    key4: {},
};

现在只需分配项目

result.key1.key11 = []
result.key1.key12 = []
result.key1.key13 = []

数组具有正整数的键，

key11

是对象属性复制，数组只能具有正整数的键数组具有正整数的键，
