A trampoline in computing is like a helper that allows a program that is running to jump to a different part of the code and then jump back to where it was before. It's kind of like playing on a trampoline, where you bounce up and down and then back up again to the same spot.
Imagine that you have a computer program that needs to do a specific task, but that task requires some additional information that the program doesn't have yet. Instead of stopping the program and waiting for the information to come in, the program can use a trampoline to jump to a function that will provide the missing information, and then jump back to where it left off to continue with the task.
It's like taking a detour on a road trip to stop at a gas station for directions and then hopping back on the highway to keep going.
Trampolines can help make programs run more smoothly and efficiently, without interrupting the flow of the program.
