Clicking an object reference to an array

Question

As far as I can see in this situation:

var x = [];
var y = {};

y.someProp='asd';

This does not work:

x.push(y);

What I want to do is add the link y to x so that later, if I "delete y;" I want it to be removed from the x array as well.

Answer 1

You mix variables, references, and objects.

Execution delete y;deletes the variable y. Since the variable no longer exists, it naturally will no longer matter. Thus, the link contained in the variable is missing.
