Understanding how to use collections properly is a vital part in writing effective C# applications. In this course, Advanced C# Collections, you'll learn how to use the full range of Microsoft collections and understand how to ensure collection elements are unique using sets, along with customizing dictionary key lookup and sorting of elements. First, you’ll develop an understanding of the principles of collection scalability, which is important to ensure performance stays acceptable when dealing with very large collections. Then, you'll discover how to make your code around collections more robust by using collection interfaces to decouple code, and read-only and immutable collections to protect your data. Finally, you'll delve into using collections in a multi-threaded scenario using the concurrent collections. By the end of this course, you'll have the knowledge needed to effectively choose the most appropriate collection for any reasonable situation, and leverage that collection following good practices.

Angular uses RxJS to create Observable data streams, but that’s just one of its many features. In this course, RxJS in Angular: Reactive Development, you will gain the ability to develop your applications with a more declarative and reactive approach using RxJS. First, you will learn RxJS terms and syntax and examine several key RxJS operators so you can better leverage this powerful technology. Next, you will discover a declarative approach to defining data streams and combining data streams to merge data from multiple sources so you can more easily display useful related data for your users. Finally, you will explore how to create streams from user actions, such as a selection, and merge the data streams with the action streams to react to those actions, automatically updating the view as needed. When you are finished with this course, you will have the skills and knowledge of RxJS needed to incorporate the power of Observable streams into your applications, providing your users with a more performant and interactive application.

At the core of state management in Angular is a thorough knowledge of the Redux pattern and the NgRx library. NgRx is a powerful library for organizing and managing state and interactions with the state in your Angular applications following the Redux pattern. In this course, Angular NgRx: Getting Started, you will learn the three principles of the Redux pattern that NgRx follows and the benefits this brings to your Angular applications. First, you will discover how to define a single store for all of your application state, access data from the store with selectors, dispatch actions using action creators, and process those actions with reducers to create new state. Next, you will explore how to handle side effects, such as asynchronous operations, with effects. Finally, you will learn how to architect your Angular applications for scale and performance using the container and presentational component patterns. When you are finished with this course, you will have a foundational knowledge of NgRx that will help you move forward to develop larger or more complex Angular application.
