What is scope and scope chain in JavaScript?
An example of an AI chatbot conversation about scope and scope chain in JavaScript.
Can you explain what scope means in JavaScript?
Sure! In JavaScript, scope refers to the current context of execution, which determines the accessibility of variables.
What about the scope chain? How does it work?
The scope chain is a series of scopes that JavaScript uses to resolve variable names. It starts from the current scope and goes up to the global scope.
Can you give me an example of how the scope chain works?
Absolutely! If you have a variable in a function, that function can access its own variables, its parent function's variables, and global variables.
