Robust and sleek Docker-based Continuous Integration as a service. I used CircleCI prior to them becoming a sponsor and I love that their free tier is powerful enough for small personal projects, even if they are private. Use this link when you sign up to let them know you came from here:

Wonder how MPJ evaluates JavaScript inline his editor. Quokka is the answer - use this link when you buy to let them know you came from here:

๐ FUN FUN FUNCTION
Since 2015, Fun Fun Function (FFF) is one of the longest running weekly YouTube shows on programming ๐
thanks to its consistency and quality reaching 200,000+ developers.
๐คฆโโ๏ธ The Failing Together concept is what makes FFF unique. Most coding content out there focus on step-by-step tutorials. We think tutorials are too far removed from what everyday development is like. Instead, FFF has created a completely new learning environment where we grow from failure, by solving problems while intensively interacting with a live audience.
Tutorials try to solve a problem. Failing Together makes you grow as a developer and coworker.
