An example of an AI chatbot conversation about function scope in programming.
What is function scope in programming?
Function scope refers to the accessibility of variables within a function. Variables defined inside a function are not accessible outside of it.
Can you give me an example of function scope?
Sure! In JavaScript, if you declare a variable inside a function using 'let' or 'var', it cannot be accessed outside that function.
What happens if I try to access a variable outside its function?
If you try to access a variable outside its function, you'll get a reference error, indicating that the variable is not defined.
Are there different types of scopes in programming?
Yes, besides function scope, there are global scope, block scope, and lexical scope, each defining variable accessibility differently.
