I learned this the hard way 😅 Coming from JavaScript. Also
i = i + 1 reassigns i, where i += 1 increments i by 1, they are not equivalent (despite what many stack overflow answers might tell you)
One uses __iadd__ and the other __add__

Hmm...we had a few people using note++ in my first job. However, we also used svn so... 🗑️🔥 😬

Thanks for the input everyone! Sometimes it really helps to hear I'm not alone in this struggle haha. 😊
