In learning Python, you took the first step in your software engineering career by learning Python's fundamentals, its elegance, and its programming principles. For the next stage of your career, let's learn how to transfer your programming knowledge to JavaScript to work on frontend tasks, including UX/UI work, form validation, frontend animations, and more. You may be familiar with rendering the frontend with Flask, but JavaScript will allow you to create user interfaces and react in real time to user input.
We'll go through the differences between the two languages, not just on a syntactical level, but also semantical: why and when we use JavaScript over Python, what their separations of concerns are, how we connect our existing HTML and CSS with JavaScript on the frontends and backends using Node.js to create engaging user experiences, and how we create full-stack applications utilizing all layers of a web application.
