Homonym: scopes (View)
A scope is a tool used to view or measure something more clearly. In the context of science, a telescope allows astronomers to observe distant celestial objects, while a microscope helps scientists examine tiny specimens like cells. Scopes enhance our ability to see details that are otherwise invisible to the naked eye.
In programming, a scope defines the visibility and lifetime of variables. It determines where a variable can be accessed within the code. For example, a variable declared within a function has a local scope, meaning it can only be used inside that function, while a variable declared outside has a global scope and can be accessed throughout the program.
