I have the following structure in my array.
const data = [
{
name: 'Book_1',
value: {
eng: 'english_book_1',
sp: 'spanish_book_1'
}
},
{
name: 'Book_2',
value: {
eng: 'english_book_2',
sp: 'spanish_book_2'
}
}
];
And trying to get a structure like this:
[
{
eng: {
Book_1: 'english_book_1',
Book_2: 'english_book_2'
}
},
{
sp: {
Book_1: 'spanish_book_1',
Book_2: 'spanish_book_2'
}
}
];
So, the array should have language keys and nested book names with values in it. I tried a couple of things but even close.
const modified = [];
const object = {};
data.forEach(el => {
Object.entries(el.value).forEach(([name, value]) => {
if (object['name']) {
}
modified.push(object);
});
});
```
Thanks.
You could reduce the array by taking an object for the language's objects.
const
data = [{ name: 'Book_1', value: { eng: 'english_book_1', sp: 'spanish_book_1' } }, { name: 'Book_2', value: { eng: 'english_book_2', sp: 'spanish_book_2' } }],
result = Object.values(data.reduce((r, { name, value }) => {
Object
.entries(value)
.forEach(([k, v]) => (r[k] ??= { [k]: {} })[k][name] = v);
return r;
}, {}));
console.log(result);.as-console-wrapper { max-height: 100% !important; top: 0; }
