Car battery died. recharging question?

so i left my light on from 5pm yesterday all throughout the night. i tried to get my car started but its dead. Ofc im going to have to jump start it. im not too intelligent when it comes to cars but i have a question concerning use of the battery after jump start. will i have to get a replacement after i jump start this battery from death because im not sure how it works...does recharging bring the dead battery back to life and good again or am i on limited time before it dies again? i understand the alternator is what recharges the battery when the engine is on so will i not have to worry about getting a new battery once i recharge and let the car run for a bit? any answers will be appreciated. please be serious and non-rude. you might know a ton about cars but not everyone does so sorry if this sounds like a stupid question to you.
