What is the best passing to functions - variables or arrays/objects?

Question

What is the best practice regarding passing data to functions - variables, or arrays(objects).

For example, I need user info for most functions. Should I pass full user

Answer 1

There's no better practice for all scenarios. Use either one depending on the purpose of your function:

• You may pass the values of individual object properties if your function doesn't care about the object.

• You should pass the object if your function is going to manipulate the object in some way, either by directly modifying its properties or by calling its methods.
