Pass array of observables to zip and read function

I need to put an array of observables to Observable.zip, but I don't know how to create a function for read values. Array is dynamically sized. Any ideas?

import {Observable} from "rxjs/Observable";
import "rxjs/add/observable/zip";


obsArray; 

functionName():Observable<any>{
  return Observable.zip(...obsArray, (arg1, arg2, arg3, ...) => {
       return { arg1: arg1, arg2: arg2, arg3: arg3, ...}
  })
}

spread the array into the zip function and receive the response object. You can run a res.length to get the length and use a for loop or run the foreach loop on it

import {Observable} from "rxjs/Observable";
import "rxjs/add/observable/zip";


obsArray; 

functionName():Observable<any>{
 return Observable.zip(...obsArray)
}
