First off, let me be clear that I am not a lawyer, and nothing I say here can be construed as legal advice. That said, your location matters a lot. Many states in the US are “right to work”, which actually means that legally you can be fired at any time and for any reason, without notice. But it also means you can do the same to your employer. Other states are not, and there are actual legal requirements for terminating an employment contract and severe penalties if you don’t follow the rules. Regardless, I feel that you almost always want to give them at least two weeks notice, and you want to try to avoid burning those bridges. But I must concede that there are times when that is simply not possible. If you’re seriously contemplating this situation, then I would urge you to find a local employment law specialist and pay them to go over your situation with you. A small amount of money invested in getting proper local legal advice can save you a great deal of pain and suffering. In other words, a months worth of coding can be very powerful — it might even save you a full hours worth of planning!
