Design patterns are not just for architects. In fact, you already use Design Patterns but probably don't know it. Observer, Facade, Iterator, Proxy - these are all patterns that allow us to better communicate our ideas with other developers. And once we understand the patterns, we can use solutions that people way smarter than us have already implemented. In this session, we'll take a look at several Gang of Four patterns that we regularly use without realizing it. Don't know who the Gang of Four is? Join us to find out.

You will learn:

• What Design Patterns are (and what they are not)
• Who the Gang of Four is and why they are important to developers
• How Design Patterns are useful to our everyday development
