Scope refers to the part of the program where the association of a name to a value is valid, and where that name can be used to refer to the value. For example, any constants or variables that you create within a function only exist in the context of the function. This means that the lifetime of objects is limited to the scope they’re created in and cannot be used outside of that code block.
