Call-by-push-value
Call-by-push-value is a fancy term that describes how computer programs handle and pass around information. Think of it like a game of hot potato, where you pass a ball (information) from one player to another.
In call-by-push-value, there are two different ways to pass the ball: "call" and "push-value."
When you "call," it's like saying "hey, other person, do something with this information!" You're asking the other player to take the ball and do something with it in their own way.
When you "push-value," it's like saying "hey, other person, take this exact ball and use it however you need to use it." You're giving them very specific instructions on how to use the information you're passing.
So why do we need two different ways to pass information? Well, it depends on the situation.
Sometimes you want to give someone complete control over information you're passing. That's when you "call" in the call-by-push-value world. Other times, you want to be very clear about how the information should be used. That's when you "push-value."
Overall, call-by-push-value is just a helpful way for computers to pass information around in a flexible and efficient way.
