do you have to wait for 4 hours everytime you lose all your hearts.please tell me!

Question

i want to know this

Answer 1

Not every time,
if we are free and can take the lesson later then we wait for the given time else we use our bits(100 bits) to refill the hearts.

Answer 2

Or type your answer carefully.
It's often by careless mistakes we lose hearts .
If you're not sure, search for the answer elsewhere before answering. If it is a piece of code, try it in a code editor first. you learn more things this way, and become a careful coder, too.
Do not be impulsive, don't speedrun or guess...
