What is the scope of variables in different programming languages?
An example of an AI chatbot conversation about variable scope in various programming languages.
What is the scope of variables in different programming languages?
The scope of a variable refers to the context in which it is defined and accessible. Different programming languages have different rules for variable scope.
Can you explain local and global scope?
Sure! Local scope means the variable is accessible only within the function or block it is defined in, while global scope means the variable can be accessed from anywhere in the code.
How does scope work in JavaScript?
In JavaScript, variables can have global, function, or block scope. Variables declared with 'var' have function scope, while 'let' and 'const' have block scope.
What about Python?
In Python, variables defined inside a function are local to that function, while variables defined outside are global. You can use the 'global' keyword to modify a global variable inside a function.
