 This short section is about answering the basic questions people have about the actual practice and career of web development.  Because, let's be honest, even if you've got a strong feeling that you like building things and web development is the right path for you, you still probably don't have a great idea of what developers actually do... and that's where everyone starts so it's okay.

In this section, we'll dive a bit deeper into relational databases and SQL in particular.  
 
 It's a bit difficult to predict how much knowledge of SQL is the right amount... if you're building a very straightforward web application, you'll likely only need to understand the basics of Create/Read/Update/Destroy operations, how to join tables together, and how to filter and order results.

The [Web Development 101 section]({{site.url}}/dir/web_development_basics/) will give you a chance to explore several of the languages and technologies you'll need to know on your journey so you have a good sense of context when you push forward into the real meaty stuff.  It gives you a taste of HTML, CSS, Javascript, Ruby, Rails, databases, Git, testing and more.  We've also created "mini-projects" that will give you a chance to test your new knowledge by actually building something (ideally with another student!).

 2. Every turn, allow the player to make a guess of a letter.  It should be case insensitive.  Update the display to reflect whether the letter was correct or incorrect.  If out of guesses, the player should lose.
