I have the following structure :
[
{
"key": "Asset Type",
"values": ["Appliances", "Electronics"]
},
{
"key": "Asset Availability",
"values": ["In Stock"]
}
]
I need to convert it to :
{
"Asset Type": ["appliances", "electronics"],
"Asset Availability": ["in stock"]
}
How can I do that?
Here is one approach using Object.fromEntries and Array.prototype.map (to transform the array into 2d-array since that's what the Object.fromEntries expect)
const items = [{
"key": "Asset Type",
"values": ["Appliances", "Electronics"]
},
{
"key": "Asset Availability",
"values": ["In Stock"]
}
]
console.log(
Object.fromEntries(items.map(({
key,
values
}) => [key, values]))
)Here is one of the simplest solution I found
const items = [
{
"key": "Asset Type",
"values": ["Appliances", "Electronics"]
},
{
"key": "Asset Availability",
"values": ["In Stock"]
}
]
let output = items.map((obj)=>{
let result = {};
result[obj.key] = obj.values;
return result;
});
console.log(output);
Another simple solution is using Array.prototype.reduce() method
const array = [
{
key: 'Asset Type',
values: ['Appliances', 'Electronics']
},
{
key: 'Asset Availability',
values: ['In Stock']
}
]
console.log(
array.reduce((acc, rec) => {
acc = { ...acc, [rec.key]: rec.values }
return acc
}, {})
)
acc = { ...acc, [rec.key]: rec.values } - why introduce this complicated destructuring, which will cause the object to be reconstructed every time? acc[rec.key] = rec.values has the same effect and is shorter and more readable
