Team Treehouse JavaScript vs Udacity

The short, engaging videos that TreeHouse provides for all of their courses make it easy to stay focused and absorb what is being taught. The short video lengths will help keep you from getting discouraged at the amount of material to be covered.

The JavaScript courses (and JavaScript related courses, such as jQuery) take the students through building various projects, such as lightboxes and web apps.

Treehouse offers well over a hundred courses and the list is growing quickly. This means that not only can you learn JavaScript with Treehouse, but they also provide courses for a variety of libraries and frameworks (such as jQuery, Node.jS, Angular.jS, and more).

Treehouse provides coding challenges throughout the courses. You code directly in their editor, and your code is checked to make sure it's correct.

Treeehouse provides an app for both iOS and Android that is easy to use.

Courses are always made available which means there is no waiting for the specific course you want to run. You can work through the courses as fast or as slow as you want.

Udacity offers a few different Nanodegrees which provide access to various different courses, project reviews and coaching support for $200/month.
Current options include Front End Web Developer, Data Analyst and Android Developer. See the full list here.

You get actual feedback from developers on your code, which is useful. Yes having your sites/apps do what it is supposed to do is important, but you need feedback to learn industry standards/best practices and other gotchas that are much harder to learn on your own.

Courses are super easy to follow, even for super dummies.
