TFW you think "This function should do XYZ" and make it do it right the first time.
So much better than when I rewrote a function 3 times, and was questioning if I even had a clue of what I am doing, before realizing I was editing the wrong csv, which is why it wasn't finding my test cases.
That these 2 things happened 15 minutes apart... That is just part of writing code, right?
