In programming, a scope is the area of code where you can access a certain variable in order to read it, change its value, and work with that variable in general.
There are four types of scopes:
- global scope
- local/function scope
- block scope
- nested scope
In this video, I'll show you examples of each scope and explain the advantages and disadvantages, as well as when to use each variable scope.
