What is the difference between scope and hoisting in JavaScript?
An example of an AI chatbot conversation about scope and hoisting in JavaScript.
What is the difference between scope and hoisting in JavaScript?
Scope refers to the accessibility of variables in different parts of your code, while hoisting is JavaScript's behavior of moving declarations to the top.
Can you give me an example of scope?
Sure! In JavaScript, a variable declared inside a function is not accessible outside of that function. That's function scope.
And what about hoisting? How does it work?
Hoisting means that variable and function declarations are moved to the top of their containing scope during compilation. For example, you can call a function before it's defined.
So, can I access a variable before it's declared?
You can access a variable before its declaration, but it will be undefined until the declaration is reached.
