What does it take to be a really good web developer? If you’re working at your first programming job, you probably found out quickly that it’s not easy. It’s one thing to watch coding tutorials, read programming books, and make portfolio sites. It’s quite another to have to build websites from spec, to meet deadlines, and most importantly, to make sure that your bosses and clients are happy! On top of all that, technology changes fast. You may feel like you have to stay on top of trends or risk becoming obsolete next year. Want to know a secret, though? You don’t have to be afraid. As you keep working, you will gain experience in your job. In the same way that you’ve learned coding, you can also learn how to perform at a high level at work. It’s possible to learn how to be a good web developer. And it’s even possible to be anindispensably good web developer. (Obviously, I can’t guarantee your job security, but you know what I mean.) My first job I’m a self-taught web developer, who never took a formal computer science course. I’ve currently been in the field for about seven years. And of course, I’ve struggled with the learning curve and with impostor syndrome. But I’ve also picked up a lot of valuable experience and skills along the way. You might find some similarities to my experience and your own. When I started out as a junior web dev in my first real job, I was beyond thrilled. But to be completely honest, I was terrified for the first two years. Every day...
1. What is Rails? Rails is a web application framework designed to work with the Ruby programming language. Sound like mumbo jumbo?! I know! Here’s the BIG idea: there is a programming language called Ruby. It’s super fun to write. In fact, the guy who first created it said that his major motivation when writing the language was to design a programming language that would make programmers happy. Nice, right? Let me give you an example. If I want to print something to the screen in PHP I need to write: echo “Hello World”; Notice the semi-colon? And what does echo even mean?!! On the other hand if I wanted to do the same thing in Ruby alls I would write is: puts “Hello World” No semi-colon, and puts may be a little… juvenile, but it makes more intuitive sense to me than echo. Seriously, when you spend hours and hours a day writing code, it’s the little things that make a HUGE difference. So, anyways, the only problem with Ruby was that it’s not designed for use on the Web. Like…you couldn’t really use it to make websites, per se. That is until… Rails! I am not sure if Rails was the first web framework for Ruby but it’s DEFINITELY the most popular. What Rails does is provide all this fancy scaffolding and stuff to make it possible to write a Ruby application and have it be a website. This sounds really abstract when you say it here, but it’s basically like this: if I were to write puts “Hello World” in an HTML document, you would just see the whole...
