What is lexical scope in programming?
Lexical scope refers to the visibility of variables in nested functions. It determines how variable names are resolved.
Can you give me an example of lexical scope?
Sure! In JavaScript, if you define a variable inside a function, it can't be accessed outside that function.
How does lexical scope differ from dynamic scope?
Lexical scope is determined at compile time, while dynamic scope is determined at runtime based on the call stack.
Why is lexical scope important in programming?
It's important because it helps avoid variable name conflicts and makes code easier to understand and maintain.
