Remove deep equal

[arik123]

Removed deep equal, as it is unneccessary - Instead just set variable every time we changed something and check it at the end.
Reason for this is performance - deep-equal is computationaly expensive recursive function, so this decreases resource usage and speeds up event loop.

Thanks for the contribution. I'm going to decline this, since deep-equal is already removed in v3, which I hope to be releasing shortly. (#295)

I've checked V3 and it does not seem like you removed deep-equal, you just replaced it with yours, but the performance problem is still there.
