Function vs module vs stub

• Module
• organise and reduce the complexity of the code by breaking it up into smaller chunks
• a set of tasks that execute when called upon
• does not have to return a value
• Function
• a procedure that is run when is called upon in the code
• returns a single value
• Similarities between module and function
• only executed when called upon
• keep code neat and clean
• good when there are task/ processes that are repeated many times throughout the program (because of efficiency)
• Stub
• a place holder for unwritten code or code that are handled remotely (i.e. another module/ functions)
• mimics the actual "to-be-developed" code but is smaller and less functional
• reminds the developer what the "to-be-developed" code is supposed to be for
