The most recent WOD I completed was Invoice1, and in this WOD I wrote a sales receipt for a set of product data. This WOD took me longer than most other WODs because there was more code to write than the others. Something I did that I would advise others to do as well is prepare your product data before starting the WOD so that it is easily accessible and you aren’t searching for it in the middle of the WOD and wasting time. Something I could have done better is make sure I am putting semicolons where they should be because I keep forgetting them.
