Reviews
Eric shown that not only he understands the subject matter of what he is teaching but also the underlying technology. With this knowledge he can provide great context to the subject that he is teaching
Eric knew not only the latest and greatest code for react / redux / javascript, but he also had us code all of the previous parts of javascript to lead up to those newer technologies to gain a more full understanding. This helped make things more clear and help us understand the basics before jumping into the advanced.
I will definitely recommend both this class, and the instructor (Eric Greene) as he has helped us to learn not only the process, but also the syntax and basic javascript. He was very patient with us, but kept us moving through the content.
The instructor, Eric, is very knowledgeable about the materials that he's teaching. He explains very well and walks through examples before we do lab exercises.
Eric knows his stuff and can react to any situation - he's very nimble, he can scale needs of everyone while satisfying the entire class... it's quite impressive.
