Re: JsInterop Array

This is not "garbage", they are "expando properties".
It shouldn't be a problem in practice for any well-coded JS lib. If your JS lib fails here, it probably means it iterates over the array using a for…in loop: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in#Array_iteration_and_for...in
As a workaround, you can probably copy the array into a JsArrayInteger:
JsArrayInteger arr = JavaScriptObject.createArray().cast();
for (int node : nodes) {
or using Elemental2 Core:
JsArray<Double> arr = new JsArray<>();
for (int node : nodes) {

Hello guys, so I'm getting crazy with this.

I need to inject a java array inside a javascript library.

The problem is that the Js library will iterate over an integer array, and if the element is not an integer it exits the function.
When I create the integer array and pass it to plain javascript array, for some reason it carries garbage inside, I already tried everything with no success.

So this is my java nodeset (https://pastebin.com/AdJqj80p)

I'm using the gwt-interop-utils -> https://github.com/GWTReact/gwt-interop-utils/blob/master/src/gwt/interop/utils/client/plainobjects/JsPlainObj.java

And when I inspect the javascript object in the browser you can see it has lots of garbage, and I cant clean it. See the nodes array I have (_clazz_0_g$,__elementTypeCategory$,_elementTypeId$"......).

And when I do the same with Js I don't have this garbage (obvious).

I already used the JsArray and everything, but no luck =/.

Do you have any Idea how to have a plain javascript array with jsInterop?

Thanks a lot.
