‫Now, before we dive really deep
‫into Node.js, Express, databases and more,
‫it's important to get a good understanding
‫of back end development in general,
‫because that's what we actually use Node.js for
‫in this course.
‫So you're gonna learn things like how the web works,
‫the request-response model, HTTP, TCP/IP,
‫static versus dynamic websites, what APIs are,
‫(chuckles) and much more.
‫And I hope that with the sections,
‫some of the things that we did in the last one
‫will then start to make more sense.
