I am currently in the second JavaScript module of the Codecademy Web Development Career Path. I am familiar with the topics. I have experienced this in the C/C++ programming language. It is exciting to know that I will have access to JavaScript in my career along with C/C++. I think this a strong combination of languages.
The next module after this will teach me how to start using JavaScript to create interactive pages. I have been longing for this part since the start of the path. Once I finish that module, I can be confident that I will have the fundamental skills to build and customize web sites. There are still many modules to complete. I am just at the 25 to 30% part of the series. My aim is to finish two more modules before the semester break.
