I would like to sort an object which you can see below. I want to add all the rating properties for each object and sort the object depending on which rating is highest.
So for example, if Intro 1 total rating is equal to 7 and Intro 2 total rating is equal to 3, then Intro 1 should be the first object.
{
'Intro 2': [
{
deckName: 'Test 2',
rating: 1
},
{
deckName: 'Test 2',
rating: 2
}
],
'Intro 1': [
{
deckName: 'Test 1',
rating: 3
},
{
deckName: 'Test 1',
rating: 4
}
]
}
Here's your data
const data = {
"Intro 2": [
{
deckName: "Test 2",
rating: 1
},
{
deckName: "Test 2",
rating: 2
}
],
"Intro 1": [
{
deckName: "Test 1",
rating: 3
},
{
deckName: "Test 1",
rating: 4
}
]
};
Let's convert it into array and sort through
const dataArr = Object.entries(data);
const sorted = dataArr.sort(
(a, b) =>
b[1].reduce((acc, curr) => {
return acc + curr.rating;
}, 0) -
a[1].reduce((acc, curr) => {
return acc + curr.rating;
}, 0)
);
And finally converting the array back to object
const obj = {};
sorted.forEach((item) => {
obj[item[0]] = item[1];
});

UPDATE
For the last cycle of converting array to object, this can be more elegant solution
const obj = Object.fromEntries(sorted);
