How does lexical scoping work?
An example of an AI chatbot conversation about lexical scoping in programming languages.
Can you explain what lexical scoping is?
Sure! Lexical scoping is a way of defining the scope of variables based on their location within the source code.
How does it differ from dynamic scoping?
In dynamic scoping, the scope is determined at runtime based on the call stack, while lexical scoping is determined at compile time.
Can you give me an example of lexical scoping in JavaScript?
Absolutely! In JavaScript, if you define a variable inside a function, it can only be accessed within that function or its nested functions.
What happens if I try to access a variable outside its scope?
If you try to access a variable outside its scope, you'll get a reference error indicating that the variable is not defined.
