const ExemCategories = [

{ ExcategoryId: 1, vSubtypeCategory: 'Police Vehicle' },

{ ExcategoryId: 2, vSubtypeCategory: 'Army Vehicle' },

{ ExcategoryId: 3, vSubtypeCategory: 'Ambulance' },

{ ExcategoryId: 4, vSubtypeCategory: 'GOV Vehicle' },

{ ExcategoryId: 5, vSubtypeCategory: 'Fire Brigade' },

{ ExcategoryId: 6, vSubtypeCategory: 'Local' }

];

const ExemKey = {

f1: "1",

f2: "2",

f3: "3",

f4: "4",

};

ExemCategories.forEach((item, index) => {

const key = `f${item.ExcategoryId}`;

const value = item.vSubtypeCategory;

ExemKey[key] = value;

});

console.log("key hh", ExemKey);

output -

key hh {

  f1: 'Police Vehicle',

  f2: 'Army Vehicle',

  f3: 'Ambulance',

  f4: 'GOV Vehicle',

  f5: 'Fire Brigade',

  f6: 'Local'

}
