JavaScript Garbage Collector

Question

Here's a somewhat difficult question. Let's say I declare an array as follows:

var arr = [1, 2, 3];

and I set the length of the array to 2 as follows:

arr.length = 2;

Would the garbage collector remove the third element from memory? Does anyone know the answer?

Answer 1

Yes it will. arr will then be [1, 2]. You can test it in the Code Playground.
