Improving your C# Skills

By: Ovais Mehboob Ahmed Khan, John Callaway, Clayton Hunt, Rod Stephens

Overview of this book

This Learning Path shows you how to create high performing applications and solve programming challenges using a wide range of C# features. You’ll begin by learning how to identify the bottlenecks in writing programs, highlight common performance pitfalls, and apply strategies to detect and resolve these issues early. You'll also study the importance of micro-services architecture for building fast applications and implementing resiliency and security in .NET Core. Then, you'll study the importance of defining and testing boundaries, abstracting away third-party code, and working with different types of test double, such as spies, mocks, and fakes. In addition to describing programming trade-offs, this Learning Path will also help you build a useful toolkit of techniques, including value caching, statistical analysis, and geometric algorithms. This Learning Path includes content from the following Packt products: • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan • Practical Test-Driven Development using C# 7 by John Callaway, Clayton Hunt • The Modern C# Challenge by Rod Stephens

Node.js, commonly called Node, is practically a requirement for doing modern web application development. In this section, we will discuss what Node is exactly, provide reasons why you need Node, and, finally, talk about where you can get Node installation instructions.

If you are already familiar with these subjects, then feel free to jump to the next section, where we discuss NPM in a similar fashion.

What is Node?

Node was created in late 2009 by Ryan Dahl. Based on Chrome's V8 engine, Node provides a JavaScript runtime built for the purpose of providing evented, non-blocking I/O (input/output) for serving web applications.

At the time, Chrome had created the fastest JavaScript engine available. At the same time, they had decided to open-source the code for it. For these two extremely compelling reasons, Node decided to use the V8 engine.

Ryan Dahl was unhappy with the performance, at the time, of the very popular Apache HTTP server. One of the problems with the way that Apache was...
