In the past month, Free Code Camp did a major restructuring of their challenge map. One such change I noticed was the removal of the Udacity OOP course that I found particularly difficult at my level. Since then, I have gone through and 'filled in the holes' where new lessons have appeared. Currently I am all caught up and about to start on Upper Intermediate Algorithm Scripting. I have been jumping back-and-forth between Treehouse and Free Code Camp, as I find the lessons on the former are strongest, while the practice excels on the latter. Working with CodePen has been great, the immediate feedback in the preview window is incredibly powerful. My favorite project by far was working with the Twitch.tv API. It was really enjoyable to see my code interact with another website. I look forward to toying with more APIs in the future.
