Tests:
  • Using spread operator

    AخA
     
    const basicData = [{id: 1}, {id: 2}, {id: 3}];
    const finalData = [...basicData, {id: 4}];
  • Using push function

     
    var basicData = [{id: 1}, {id: 2}, {id: 3}];
    basicData.push({id: 4});
  • Add to last index of array

     
    var basicData = [{id: 1}, {id: 2}, {id: 3}];
    basicData[basicData.length] = {id: 4};
