I am attempting to retrieve the value feature_1 associated with the key name from the array data. I then aim to set feature_1 as the key of another array asset, with an array as its corresponding value.
For example:
//input:
data: {
name: "feature_1",
value_a: 1,
value_b: 2
}
//Output:
asset: {
feature_1:[1,2]
}
If you're looking for a solution, consider the following code snippets:
let data = {};
if ('name' in asset) {
let tmp = [];
for (k in asset){
if (k != 'name') tmp.push(asset[k]);
}
data[asset['name']] = tmp;
}
Alternatively, if your interpreter supports ES6, you can try this approach:
let {name, ...v} = asset;
let data = {[name]: Object.values(v)};
If a JSON object supports the same keys (which it doesn't seem to), you can achieve it like this:
let data= {
name: "feature_1",
value_a: 1,
value_b: 2,
value_x: 500,
name: "feature_2",
value_a: 17,
value_b: 21,
value_x: 510
}
console.log(
Object.entries(data).reduce((a,[key,value],index)=> {
if (key==='name')
return {index, assets: {...a.assets, [value]:[]}};
return {
index : a.index,
assets : {
...a.assets,
[Object.entries(a.assets)[a.index][0]] : [...Object.entries(a.assets)[a.index][1],value]
}};
},{index:0,assets:{}}).assets
);However, we are aware that the proper way is using separate array rows.
To achieve this, you can follow the steps below:
const object = {
details: {
title: "feature_1",
value_x: 1,
value_y: 2
}
};
const result = {
items: {
[object.details.title]: Object.values(object.details).filter(item => item !== object.details.title)
}
}
