re: Quick question- what happens when you push an array into itself? VIEW POST


When you pushed an array inside itself, you don't create infinite arrays.

Just like pushing any other object, you have stored a reference (or pointer) to array1 (let's call it "array1") inside the array1 object itself.

When you store other objects, you go from array1 -> items -> item1 which gives you all contents of item1.

Now you go from array1 -> items -> array1 which gives you all the contents of array1. Guess what contents does array1 has? - a reference to array 1.

This is giving you an illusion that you are going down the layers of array infinitely. But instead what is happening is that you are really going in a circle.

Imagine a house with 2 doors. When you enter the house through door1. You see door2 inside the house (your array). When you go through door2, you find yourself standing in front of door 1. You keep entering the same house again and again, creating an illusion that there are infinite houses within your house


TLDR: pointers can create cycles.


Also you can do stupid shit like this in Linux by creating a symlink of a directory that points to the parent directory causing recursive directories.

Cool. But why would you want to do that?

Absolutely no reason to do this. Just a fun discovery.


Wow! Now this makes total sense. Thanks Rishab.
Meanwhile, does this not require some computation power?
