What is function scope in programming?

What is function scope in programming?

Function scope refers to the visibility of variables within a function. Variables declared inside a function are not accessible outside of it.

Can you give me an example of function scope?

Sure! In JavaScript, if you declare a variable inside a function using 'let' or 'var', it can't be accessed 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 a reference error, indicating that the variable is not defined.

Are there any exceptions to function scope?

Yes, in JavaScript, variables declared with 'var' can be hoisted, but they still remain function-scoped.
