Can you explain lexical scope?
An example of an AI chatbot conversation about lexical scope in programming.
Can you explain lexical scope?
Sure! 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?
Of course! In JavaScript, if you have a function inside another function, the inner function can access variables from the outer function.
What happens if I try to access a variable that is out of scope?
If you try to access a variable that is out of scope, you'll get a reference error, as the variable is not defined in that context.
Is lexical scope the same as dynamic scope?
No, lexical scope is determined at compile time based on the structure of the code, while dynamic scope is determined at runtime.
