An example of an AI chatbot conversation about scope in JavaScript.
What is scope in JavaScript?
Scope in JavaScript refers to the accessibility of variables, functions, and objects in some particular part of your code.
Can you explain the difference between global and local scope?
Global scope means variables are accessible from anywhere in the code, while local scope means they are only accessible within a specific function.
What are block scope and function scope?
Block scope is created by curly braces {} and is used in constructs like if statements and loops. Function scope is created by functions, where variables are only accessible within that function.
How does the 'let' keyword affect scope?
The let keyword allows you to create block-scoped variables, meaning they are only accessible within the block they are defined.
