I need to push array to an object inside an object not able to perform this task. I am working on angular 6



Here is an example.



 abc = { data: { name: '', version: '', type: '', ports: , vm: } };



  let hostlist = ['1234.Vm', '5678.Vm', '6789.Vm'];

//Need to push hostlist data to adc.data.vm

this.adc.data.vm.push(hostlist);

//this output is array inside array

this.adc.data.vm.concat(hostlist);

// concat cont work gives empty array


I need the output in this format 



{ name: '', version: '', type: '', ports: , vm:['1234.Vm', '5678.Vm', '6789.Vm'] }





javascript

          You can either push with the spread operator or reassign adc.data.vm to the result of concat (since concat returns a new array without changing existing arrays):



          Method 1: push() using the spread operator






          // method 1: push with spread operator
          
let adc = {
          
  data: {
          
    name: '',
          
    version: '',
          
    type: '',
          
    ports: ,
          
    vm: 
          
  }
          
};
          
let hostlist = ['1234.Vm', '5678.Vm', '6789.Vm'];
          

          
adc.data.vm.push(...hostlist);
          
console.log(adc);





          Method 2: Reassign to the result of concat






          let adc = {
          
  data: {
          
    name: '',
          
    version: '',
          
    type: '',
          
    ports: ,
          
    vm: 
          
  }
          
};
          
let hostlist = ['1234.Vm', '5678.Vm', '6789.Vm'];
          

          
adc.data.vm = adc.data.vm.concat(hostlist);
          
console.log(adc);

            You could always assign the object to that property:



            abc.data.vm = abc.data.vm.concat(['1234.Vm', '5678.Vm', '6789.Vm']);

                      You could always assign the object to that property:



                      abc.data.vm = abc.data.vm.concat(['1234.Vm', '5678.Vm', '6789.Vm']);
