How do different programming languages handle argument passing?

Different languages have various methods for argument passing, such as pass-by-value, pass-by-reference, and pass-by-name. For example, in C, arguments are typically passed by value, while in Python, they are passed by reference.

Can you explain pass-by-value and pass-by-reference?

Sure! Pass-by-value means that a copy of the variable is passed to the function, so changes made to the parameter do not affect the original variable. In contrast, pass-by-reference means that a reference to the original variable is passed, allowing the function to modify the original variable.

Which languages use pass-by-reference?

Languages like C++, Java (for objects), and Python (for mutable objects) use pass-by-reference. This allows functions to modify the original data.

What about JavaScript?

JavaScript uses pass-by-value for primitive types and pass-by-reference for objects. This means that when you pass an object to a function, the function can modify the original object.
