About The Professor

Jason Millhouse

Jason Millhouse

Jason has been teaching since he was a kid and has racked up a bunch of Education degrees since then. A glutton for punishment, he's nearly finished with a Computer Science degree, too. He's built and taught curriculum for over 100 DVDs worth of educational material, barely living to tell the tale. He spends his lack of spare time wishing he could play a few video games, impersonating the British voice of his corgi, Charlie, and being the actual Voice of the University of Central Florida Marching Knights. Reach him with @ItsThrillhouse on Twitter.

Another great course. From what i've seen so far, i have to say Jason does the best courses in Code School. This course proves it once again. The only thing i was missing in this course was the complexity of the challenges, which was far higher in the Javascript Roadtrip courses. Still, a good course overall. :) 10/10, would do again.

Favorite codeschool course so far. Excellent pedagogical organization, clear, informative, and beautifully designed. The test-style challenges (multiple choice, true/false, fill-in-the-blank) were also a very nice augmentation to the code challenges...they definitely helped conceptual knowledge congeal. P.S. Would love a course on famo.us!

Great course. This course adds polish to all of the Javascript knowledge taught in Road Trip parts one through three. The namespacing, module pattern, ternary, and additional operator knowledge alone is enough to really give your development knowledge a great polish. While some of the knowledge in this course may be redundant to seasoned Javascript developers, I think there's a lot to absorb for everyone. I walked away from the JS Best Practices course and immediately put what I learned to use to make my code more elegant.

You Must Take This Course. After taking the JS Roadtrip courses, this one both reinforces previously learned concepts as well as builds on them. I also loved the mixed style of learning, as this course not only has terminal-style challenges, but also fill-in-the-blanks. To top it off, the RPG-esque theme was way fun, without being over the top (I thought the road trip js prompts were a little to lengthy). Overall, this was immensely helpful and entertaining. A++
