Forming Object Using Filter and Map method

Issue

I have a object which contains information of sources:

multiplierInformation = [ { groupName: 'RAW MATERIALS', sourceType : [ { name: 'Cement', quantityDescription: '', quantityFlag: false } ] } ]

I need to filter out values based on name property.

Please suggest.

Solution

basically this should work:

let arrayComingFromBackend = [{
  controls: [],
  count: 1,
  description: "",
  id: null,
  key: "cement",
  name: "Cement",
  quantity: 1,
  sourceFormulaId: "31de1317-f5a5-4620-a854-fcfed851ac78",
  sourceSpecifications: [],
  sourceType: "RAW MATERIALS",
  usageParameters: [],
  length: 1
}];

let multiplierInformation = [{
    groupName: 'RAW MATERIALS',
    sourceType: [{
      name: 'Cement',
      quantityDescription: '',
      quantityFlag: false
    }]
  },
  {
    groupName: 'AIR TRANSPORT',
    sourceType: [{
        name: 'Helicopter',

      },
