Since our curriculum’s inception in 2012, we've learned a lot about what a programmer needs to know to be able to contribute to a company from day one. A core skill of an effective web developer is the ability to pick up a programming language quickly and to build something with it, even if they have not used that language before. By learning multiple languages up front, you’ll gain confidence with the learning process itself, so you’re ready for whatever your career throws at you.
Between languages, you will be able to clearly see different syntaxes and data handling, but you will also see that most web programming languages are remarkably similar. Having a strong understanding of concepts like OOP, MVC, and Database Scaling is the best way to prepare for picking up new skills quickly. You'll avoid getting stuck in one language, and you'll become a more versatile and skilled web developer.
