Possible to do in one loop?

 "branchMaterials": [
        {
            "branchId": 1,
            "materialBalances": [
                {
                    "balance": 20.0,
                    "consignmentMaterialId": 59,
                    "branchId": 1,
                    "materialName": "test"
                },

 "branchMaterials": [
        {
            "branchId": 1,
            "materialBalances": [
                {
                    "balance": 20.0,
                    "consignmentMaterialId": 59,
                    "branchId": 1,
                    "materialName": "test"
                },

api returns this, shouldve been grouped by materialName can we do that in one loop?

Solution

groupBy(branchMaterials.flatMap(branchMaterial => branchMaterial.materialBalances), materialBalance => materialBalance.materialName)

groupBy(branchMaterials.flatMap(branchMaterial => branchMaterial.materialBalances), materialBalance => materialBalance.materialName)

better way to do this?

groupBy(branchMaterials.flatMap(branchMaterial => branchMaterial.materialBalances), materialBalance => materialBalance.materialName)

groupBy(branchMaterials.flatMap(branchMaterial => branchMaterial.materialBalances), materialBalance => materialBalance.materialName)

Thanks you're a god @nickserv

Note that I'm using

groupBy

groupBy

from the TC39 proposal

I'm using lodash so no worries

NickServ•8/2/23, 9:51 PM

You'll have to use a supported environment or polyfill it, and then replace it with or depending on what you want it to return

NickServ•8/2/23, 9:51 PM

You don't need lodash for this imo

lolking0OP•8/2/23, 9:51 PM

we already use it in the project

NickServ•8/2/23, 9:52 PM

In that case you should probably use their primitives instead of my callback functions

okk
