• Learn what are the goals of RxSwift, compare the pros and cons of learning and using RxSwift, and become familiar with the foundation of RxSwift: the observable.
• See how to use filtering operators to apply conditional constraints to next events and only pass through the elements you want to subscribers.
• Review concepts and go through several examples of putting the most widely-used transforming operators in RxSwift to work.
• Get introduced to what you will be learning about in this part: joining observable sequences together.
