Overview of this book

If you are looking for a programming language to develop flexible and efficient applications, JavaScript is an obvious choice. Advanced JavaScript is a hands-on guide that takes you through JavaScript and its many features, one step at a time. You'll begin by learning how to use the new JavaScript syntax in ES6, and then work through the many other features that modern JavaScript has to offer. As you progress through the chapters, you’ll use asynchronous programming with callbacks and promises, handle browser events, and perform Document Object Model (DOM) manipulation. You'll also explore various methods of testing JavaScript projects. In the concluding chapters, you'll discover functional programming and learn to use it to build your apps. With this book as your guide, you'll also be able to develop APIs using Node.js and Express, create front-ends using React/Redux, and build mobile apps using React/Expo. By the end of Advanced JavaScript, you will have explored the features and benefits of JavaScript to build small applications.

Summary


Code testing is one of the most important skills a developer can have. Testing code is like going to the gym. You know it's good for you, but it can often be difficult to begin. In this chapter, we discussed the reasons to test code, several types of code tests, and several JavaScript code testing frameworks. Code tests need to be done to ensure program correctness. Test-Driven Development is one of the simplest ways to begin integrating tests into a project. TDD revolves around writing tests that outline the requirements of any feature or function added, before any implementation code is written. There are many forms of code tests. In this chapter, we covered unit tests, functional tests, and integration tests. These types of code tests are the most common and are generally built from one of two methodologies: black box and white box. Functional, unit, and integration tests can all be built in many of the frameworks covered in the previous topic.

In the next chapter, we will cover...
