Here's my attempt at an iterator implementation, but the `while(true)` makes me nervous.  Any other sources / implementations welcome.





    var paramsString = "Name=Fiona&Type=Hippo";
    var urlParams = new URLSearchParams(paramsString);
    var entries = urlParams.entries();

    while(true) {
      var iterator = entries.next()
      if (iterator.value) {
        console.log(iterator.value[0] + ": " +
                    iterator.value[1])
      }
      if (iterator.done) {
        break;
      }
    }

I'm using [`URLSearchParams`][1] which will return an iterator object, but isn't supported in IE. I added a [polyfill][2], but now IE doesn't have any native support for the returned [iterator object][3] as it doesn't implement the [`for...of`][4] syntax.

What is the preferred syntax for calling an iterator object without `for..of`?

Here's the ES6 `for...of` syntax:



    var paramsString = "Name=Fiona&Type=Hippo";
    var urlParams = new URLSearchParams(paramsString);
    var entries = urlParams.entries();

    for(pair of entries) { 
      console.log(pair[0], pair[1]); 
    }






    var paramsString = "Name=Fiona&Type=Hippo";
    var urlParams = new URLSearchParams(paramsString);
    var entries = urlParams.entries();

    for(pair of entries) { 
      console.log(pair[0] + ": " + pair[1]); 
    }




    <script src="https://cdn.rawgit.com/WebReflection/url-search-params/v0.10.0/build/url-search-params.js"></script>



I'd love to find a canonical source that implements the calling syntax for iterator objects back to older browsers without relying on transpiling `for...of`.
