How do lexical scopes work?

Can you explain what lexical scope is in programming?

Sure! Lexical scope refers to the visibility of variables in nested functions. It determines how variable names are resolved.

How does it differ from dynamic scope?

In dynamic scope, a variable's value is determined by the call stack at runtime, while lexical scope is determined by the structure of the code.

Can you give me an example of lexical scope 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 lexical scope, you'll get a reference error, as the variable is not defined in that context.
