About the course

This course comes from my mentoring and coaching sessions. Often, the people I work with have experience with Python, but not Java or JavaScript. There's never been a reason to learn so they haven't. With AI capability being what it is, now the people I coach need to know why, when, and how to choose which to use. That means they need to know both more at the architectural level rather than the command and syntax level.
