What is function scope?
An example of an AI chatbot conversation about function scope in programming.
Can you explain what function scope is in programming?
Sure! Function scope refers to the visibility of variables within a function. Variables defined inside a function are not accessible outside of it.
Why is function scope important?
Function scope is important because it helps prevent variable name conflicts and keeps the global namespace clean, reducing bugs.
Can you give me an example of function scope?
Of course! In JavaScript, if you declare a variable inside a function using 'let' or 'var', it won't be accessible 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 an 'undefined' error or a reference error, depending on how it's declared.
