Code in the real world is more than just data-in/data-out that you typically see in short coding tutorials. During the development of larger software projects, there will be a number of paradigms for organizing complex code you will be expected to know, including functional and object-oriented programming.
Regardless of what framework or backend stack your employer uses for your codebase, almost all web applications have a frontend that can be viewed by the user in a browser. HTML and CSS are the basis of all visible content on the web. We emphasize a strong foundation in these technologies to ensure that your project is functional, accessible, and visually appealing.
The days of working alone are over. Having experience working on an engineering team is crucial for job interviews. All code needs to be stored somewhere, so “source control” is the main way that engineers can work collaboratively on code. There were many “source controls” in the past, but over the last ten years, almost all companies have switched to using git.
Recursion is an advanced concept that is easy to skip over - but any CS grad will have a solid understanding of this topic. It actually appears in the real world frequently, especially when dealing with file systems. Recursion is not simply a technique; it is an entirely different approach to thinking which is common in Functional paradigm code. It is also used in the ideal solutions to many Leetcode-style technical interview problems.
