I've got a object a bit like this:
{
"FORD": [
{
"ManufacturerName": "FORD",
"Model": "Focus",
"Price": "12345"
},
{
"ManufacturerName": "FORD",
"Model": "KA",
"Price": "11111"
},
{
"ManufacturerName": "FORD",
"Model": "Focus",
"Price": "22222"
}
],
"HONDA": [
{
"ManufacturerName": "HONDA",
"Model": "JAZZ",
"Price": "98765"
},
{
"ManufacturerName": "HONDA",
"Model": "JAZZ",
"Price": "33333"
}
]
}
I've got this far using lodash code like this:
let myTest = _.chain(obj)
.sortBy('ManufacturerName')
.groupBy('ManufacturerName')
What I'm trying to do also also group it by Model, so result will look something like this:
{
"FORD": [
{
"Focus": [
{
"ManufacturerName": "FORD",
"Model": "Focus",
"Price": "12345"
},
{
"ManufacturerName": "FORD",
"Model": "Focus",
"Price": "12345" }
],
"KA": [
{
"ManufacturerName": "FORD",
"Model": "KA",
"Price": "11111"
}
]
}
],
"HONDA": [
{
"JAZZ": [
{
"ManufacturerName": "HONDA",
"Model": "JAZZ",
"Price": "33333" },
{
"ManufacturerName": "HONDA",
"Model": "JAZZ",
"Price": "98765" }
]
}
]
}
Thanks.
Map the object with _.mapValues() and group each each array (v) by the Model:
const obj = {"FORD":[{"ManufacturerName":"FORD","Model":"Focus","Price":"12345"},{"ManufacturerName":"FORD","Model":"KA","Price":"11111"},{"ManufacturerName":"FORD","Model":"Focus","Price":"22222"}],"HONDA":[{"ManufacturerName":"HONDA","Model":"JAZZ","Price":"98765"},{"ManufacturerName":"HONDA","Model":"JAZZ","Price":"33333"}]}
const result = _.mapValues(obj, v => _.groupBy(v, 'Model'))
console.log(result)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.21/lodash.min.js" integrity="sha512-WFN04846sdKMIP5LKNphMaWzU7YpMyCU245etK3g/2ARYbPK9Ub18eG+ljU96qKRCWh+quCY7yefSmlkQw1ANQ==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>Or using a chain:
const obj = {"FORD":[{"ManufacturerName":"FORD","Model":"Focus","Price":"12345"},{"ManufacturerName":"FORD","Model":"KA","Price":"11111"},{"ManufacturerName":"FORD","Model":"Focus","Price":"22222"}],"HONDA":[{"ManufacturerName":"HONDA","Model":"JAZZ","Price":"98765"},{"ManufacturerName":"HONDA","Model":"JAZZ","Price":"33333"}]}
const result = _(obj)
.mapValues(v => _.groupBy(v, 'Model'))
.value()
