How to pass a Construct 3 array to a JS function

Hi everyone, first of all thanks to the Construct 3 team. It's an amazing product.

And thanks to the entire community for your valuable help !

Let me explain my challenge:

I have a Construct 3 array, initialized, named arrMainDeck

I have a file in my project "main.js" which I import for events.

Inside this js file I have a function parseHand that expects one parameter (array)

	function parseHand(handArr) {

	const JS_arrDeck= runtime.objects.arrMainDeck.getFirstInstance();
	runtime.globalVars.tempResult= parseHand(JS_arrDeck);

	//const jsArray = [];
	// loop the construct 3 array and push values with getAT
	//jsArray.push(c3Array.getAt(x, y));

when you get an instance of the array object using runtime.objects.arrMainDeck.getFirstInstance();

you are not getting a native js array, you are getting a construct object

I think construct arrays are always stored as 3d arrays, regardless of what dimensions you set, I don't think there is an exposed method to extract that 3d array data, you could do like you suggest and use GetAt to reconstruct the array.

I usually tend to avoid array objects in construct, if I only need 1 dimensions (list)

you could use a JSON object instead it has similar functionality to support arrays.

but the advantage with json you can get the raw json value in js

ahh ok, that is what I thought.. that I was getting a Construct 3 object, not a native js Array.

thanks for your reply.. I'll consider what is best, to use JSON or the GetAt workaround
