How to convert this array element in a string in typescript?

I have this array called fieldlist which is coming from the below http.get request in angular 2 component. I have declared it like this .

                   fieldlist: string[] = [];

then I assigned its value using iteration of json resposne. 

               this.http.get(getform_endpoint,requestOptions).map((res: 
                                        Response) => res.json()).subscribe(
                          res => { 

                   this.FormData = res.schema;


                     res.fields.forEach(element => {
                         this.fieldlist.push(element);
                     });


          });

Now in another function like this

         create_hidden_qp() {


            let elementsnamevalue = this.fieldlist.join();
            console.log("hello", this.fieldlist.join());

      }

when I convert it to string using this lines it gives me blank "" response

but when I print it like this 

                 console.log("hello", this.fieldlist);

I am able to see the perfect array like this. 

           hello[] 0 :"userroleid" 1: "ruletype" 2: "employeeid"

So what I am missing?

A) wrong declaration? b) wrong assigment? c) wrong access to array elements?

You should call the create_hidden_qp after your request has finished:

this.http.get(getform_endpoint,requestOptions).map(r => r.json()).subscribe(res => { 
  this.FormData = res.schema;

  res.fields.forEach(element => {
    this.fieldlist.push(element);
  });

  this.create_hidden_qp();
});
