Functions and procedures might look alike, but here's the difference:

Definition:

• Functions give you a result or answer.
• Procedures just do a job or task.

Parameters:

• Both can use parameters (these are kind of like the ingredients needed for a recipe).
• However, functions usually take values to work something out.

Return Values:

• Functions always give you a return value, which is the answer you were looking for.
• Procedures, on the other hand, don’t give anything back.

So, remember:

• Use functions when you need an outcome or answer.
• Use procedures for tasks that don’t have a direct result!
