College Dropouts: Should I quit school if I want to be a web/front-end developer?

IMHO undergrad is important. It teaches you how to learn. It makes it muscle memory. By focusing on just front-end this early you are limiting your career opportunities. A 4 year degree shows employers you are dedicated and won't bail on them in 1->2 years. There are still plenty of people in the industry that wouldn't hire a college drop out or someone from a non-top-tier school. At the very least those people would give you a really hard time before giving you a chance. In short it limits your options. The tone of your question assumes that a college degree is not required for front end dev and that "front end is easier than backend." To which I say, "have you ever developed a non-shitty frontend heavy application?" Concepts of caching, network latency, and query performance come up daily. A healthy knowledge of design patterns is necessary to get anywhere that doesn't look like spaghetti code. It is serious business. If you want to get good at it first learn the basics of computer science. Learn about programming paradigms, learn about algorithms, caching, some networking, some security, and do extra work developing websites for people on the side. You won't learn front end at school, but you won't learn CS fundamentals elsewhere.

You don't necessarily need a degree for a tech startup, especially if you have a plan for success and you can get the knowledge you need elsewhere. The value of college if you want to get into web developing though is that you'd have easy access to a ready network of potential employees and collaborators, as well as some legitimacy or ethos to present to potential investors. One of my friends got into an internship at Riot through our college and that taught him more about the industry than college itself. Although one can argue that he would not have access to that internship without being in college, the point stands that you don't need college to learn the skills. Once he graduated, he took a few of his classmates and using crowdsource and funding he's got his own startup creating custom alternative keyboards. One of his projects is a wearable glove keyboard that's an alternative to output control devices if mobility is restricted-- especially if say while doing deep-sea exploration in restrictive protective gear or in a super-small submersible where space is a concern. I think he's working on engineering that particular keyboard for spacewalks now. College was instrumental for him in that he was exposed to lots of ideas about what the industry was lacking, without being exposed to all the other ideas he would not be able to see what was missing. If you can overcome these problems, I don't see why you wouldn't be able to succeed.
