javascript - 根据不同的键但相同的值合并 2 个对象数组

Question

我已经提交了下面列出的问题，但没有得到相关答案。

1. How can I merge properties of two JavaScript objects dynamically?
2. merge two json object based on key value in javascript
3. Merge two array of objects based on a key

我有 2 个对象数组，

OBJ1 -

[
    {
        "ID": 58895,
        "step": "Outage Agreed w/ Business"
    },
    {
        "ID": 58896,
        "step": "GMLC/E911/CMAS Significant"
    }
]

OBJ2 -

[
    {
        "type": "verification_step",
        "value": "GMLC/E911/CMAS Significant"
    },
    {
        "type": "verification_step",
        "value": "Outage Agreed w/ Business"
    }
]

我希望输出包含基于字符串值的单个对象中的两个值，即

[
    {
        "ID": 58896,
        "type": "verification_step",
        "step": "GMLC/E911/CMAS Significant"
    },
    {
        "ID": 58895,
        "type": "verification_step",
        "step": "Outage Agreed w/ Business"
    }
]

请给我建议出路。 (ES6 解决方案 - 非常感谢)

编辑

被指定为重复的第三个引用不是这种情况。键应保持“step”并且数据应合并。

合并两个数组后，您可以使用reduce()。

const arr1 = [ { "ID": 58895, "step": "Outage Agreed w/ Business" }, { "ID": 58896, "step": "GMLC/E911/CMAS Significant" } ] 

const arr2 = [ { "type": "verification_step", "value": "GMLC/E911/CMAS Significant" }, { "type": "verification_step", "value": "Outage Agreed w/ Business" } ]

const res = [...arr1,...arr2.map(({value,...rest}) => ({step:value,...rest}))].reduce((ac,a) => {
  let k = a.step;
  ac[k] = {...ac[k],...a} || a;
  return ac;
},{})
console.log(Object.values(res))
