What is variable scope in programming languages?

Variable scope refers to the accessibility of variables in different parts of a program. It determines where a variable can be used.

Can you explain the difference between local and global scope?

Sure! Local scope means the variable is accessible only within a specific function or block, while global scope means the variable can be accessed anywhere in the program.

How does variable scope work in JavaScript?

In JavaScript, variables can have global scope, function scope, or block scope (using 'let' and 'const'). Global variables are accessible everywhere, while function-scoped variables are only accessible within the function.

What about Python? Is it similar?

Yes, Python also has local and global scopes. Variables defined inside a function are local, while those defined outside are global. However, Python uses the 'global' keyword to modify global variables inside a function.
