i have a return like this
[
{
"tripw3": "1"
},
{
"tripw1": "2"
},
{
"tripw1": "3"
},
{
"tripw2": "4"
},
{
"tripw2": "5"
},
{
"tripw3": "6"
},
{
"tripw3": "7"
}]
and I want to make the above result be
[
{
tripw3: ["1", "6", "7"],
tripw2: ["4", "5"],
tripw1: ["3", "2"]
}]
Until now I’m still confused to make this happen.
>Solution :
You cane easily acheve the result using reduce, Object.keys and forEach
const arr = [
{
tripw4: "1",
},
{
tripw4: "2",
},
{
tripw4: "3",
},
{
tripw4: "4",
},
{
tripw4: "5",
},
{
tripw4: "6",
},
{
tripw4: "7",
},
];
const result = [arr.reduce((acc, curr) => {
Object.keys(curr).forEach((k) => acc[k] ? acc[k].push(curr[k]) : (acc[k] = [curr[k]]));
return acc;
}, {})];
console.log(result);/* This is not a part of answer. It is just to give the output full height. So IGNORE IT */
.as-console-wrapper { max-height: 100% !important; top: 0; }
