I want to transform this array of objects using RamdaJS. From this array of objects
let children = [
{ "name": "Bob", "age": 8, "father": "Mike" },
{ "name": "David", "age": 10, "father": "Mike" },
{ "name": "Amy", "age": 2, "father": "Mike" },
{ "name": "Jeff", "age": 11, "father": "Jack" }
]
into this array of objects
let fatherAndKids = [
{
"father": "Mike",
"count" : 3,
"kids": [
{ "name": "Bob", "age": 8 },
{ "name": "David", "age": 10 },
{ "name": "Amy", "age": 2
}
]
},
{
"father": "Jack",
"count" : 1,
"kids": [
{ "name": "Jeff", "age": 11 }
]
}
]
Here's what i did so far. But i failed to remove the father keys from kids's array
R.pipe(
R.groupBy(R.prop('father')),
R.map(kids => ({
father: R.head(kids)["father"],
count: kids.length,
kids: kids
})),
R.values()
)(children)
