I have acquired a solid understanding of the basics of these four technologies. I have completed all of these courses multiple times and took notes to really understand why and how to implement each technology appropriately. Though I learned a lot of fundamental knowledge through these tutorials, the majority of of my understanding came through building many different personal projects utilizing each of these technologies for practice.
Youtube has also been a very powerful resource for strengthening my understanding of any subject I am working on. I plan on working in the web development industry by the end of 2018. Other skills I have also learned in the process are Git and Github, the basics of SASS, Command line, Bootstrap and WordPress, which is what this site was created with.
