Push and pop array inside array

I've recently started using Construct 3, and I've noticed that the handling of arrays is a bit different than in other programming languages (at least as far as the event sheet is concerned).

I would need to insert inside a cell of an array, another array, and then remove it and get the array just removed.

Using normal JS I would like to recreate this code:

	myArray = []
	myArray.push([a, b])
	var [a,b] = myArray.pop()

You first push 'a' then on grabbing the index of the new row you pushed you can set at y, 'b' goes to x,1 for example.

a construct array can only hold text or numbers

so you could push a second array as JSON, then convert it back to an array when pop it out

The Json object would be a better choice as its arrays inside arrays.

Although a bit more contrived.

Thank you for your responses! :)
