How to merge array of objects with same key
I have one array with multiple object,want to merge them by same keys without losing their values.
I try some of answer in stakoverflow but none of them help me.i want to do this with map/reduce but i don't know how can i retrieve key name of every object to check them.
let rows = [
{ row1: [{ val: "row1-val1" }, { val: "row1-val2" }] },
{ row1: [{ val: "row1-val3" }, { val: "row1-val4" }] },
{ row1: [{ val: "row1-val5" }, { val: "row1-val6" }] },
{ parag: { text: "sample test" } },
{ row2: [{ val: "row2-val1" }, { val: "row2-val2" }] },
{ row2: [{ val: "row2-val3" }, { val: "row2-val4" }] },
{ row2: [{ val: "row2-val5" }, { val: "row2-val6" }] }
];
i want this result:
let rows = [
{
row1: [
{ val: "row1-val1" },
{ val: "row1-val2" },
{ val: "row1-val3" },
{ val: "row1-val4" },
{ val: "row1-val5" },
{ val: "row1-val6" }
]
},
{ parag: { text: "sample test" } },
{
row2: [
{ val: "row2-val1" },
{ val: "row2-val2" },
{ val: "row2-val3" },
{ val: "row2-val4" },
{ val: "row2-val5" },
{ val: "row2-val6" }
]
}
];

You can do it with help of reduce
let rows = [{ row1: [{ val: "row1-val1" }, { val: "row1-val2" }] },{ row1: [{ val: "row1-val3" }, { val: "row1-val4" }] },{ row1: [{ val: "row1-val5" }, { val: "row1-val6" }] },{ parag: { text: "sample test" } },{ row2: [{ val: "row2-val1" }, { val: "row2-val2" }] },{ row2: [{ val: "row2-val3" }, { val: "row2-val4" }] },{ row2: [{ val: "row2-val5" }, { val: "row2-val6" }] }];
let op = rows.reduce((o,c)=>{
let key = Object.keys(c)[0];
if(o[key]){
o[key].push(...c[key]);
} else {
o[key] = c[key];
}
return o;
},{})
console.log(op)
