Afternoon Coffee

Reflection exercise

---

Over break, reflect on and discuss the following:

• A common refrain in software engineering is “Don’t Repeat Yourself”. How do the techniques we’ve learned in the last lessons help us avoid repeating ourselves? Note that in practice there is some nuance to this and should be balanced with doing the simplest thing that could possibly work.
• What are the pros / cons of making a variable global or local to a function?
• When would you consider turning a block of code into a function definition?
