This looks awesome! I'll be following this - I'm a junior web dev, and very eager to learn more.
I'm currently enrolled in LambdaSchool's Full Stack Web Dev course (just started a few days ago!), and the javascript unit is coming up in a few months. I definitely see it kicking my ass haha - so looking at applications like this inspires me.
Thanks so much and keep up the great work! Once my skills are up to par I'll have to give this a try on my own :D
