I have an object that looks like this:
const dataObj =
{"Tom-29":[
{ "number": 12, "string": "hi"},
{ "number": 40, "string": "bye"}
]}
I want something like below and result sorted by number
[
Name:"Tom",
Age:29,
[{"number": 12, "string": "hi"},
{"number": 40, "string": "bye"}]
];
How would i do this ? I tried below approach .
const arr =Object.entries(dataObj).map(itm=>({...itm,Name:itm[0]}));
Please help me to resolve
You can use the object key and append it to each of it's children as a name.
const dataObj =
{"Tom-29":[
{ "number": 12, "string": "hi"},
{ "number": 40, "string": "bye"}
]}
const results = Object
.keys(dataObj)
.map(k => {
dataObj[k].forEach(i => {
i.name = k.split('-')[0];
i.age = k.split('-')[1];
});
return dataObj[k]
})
.flat();
console.log(results);
Iterate the dataObj entries with Array.flatMap(), extract the name and age from the key, and then map the values, and add the properties to the original object using array spread:
const dataObj = {"Tom-29":[{"number":12,"string":"hi"},{"number":40,"string":"bye"}]}
const result = Object.entries(dataObj)
.flatMap(([key, values]) => {
const [name, age] = key.split('-')
return values.map(v => ({
name,
age: +age,
...v
}))
})
console.log(result);
