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.

Types of Testing

Software testing comes in many different forms. In this section, we will discuss the different methodologies for testing code and cover the most common types of code tests.

Black Box and White Box Testing

There are two methodologies to testing code, black box and white box. The term black box signifies a system where the internal workings are not known. The only way the system can be observed is through its inputs and outputs. A white box system is a system where the internal workings are known. It can be observed through its inputs, outputs, and exact internal workings. Black box and white box systems could be anything from a software program, to a mechanical device, or any other system.

Black box testing refers to software testing when the internal structure or implementation of the code is not known to the tester. We are only able to observe the inputs to, and outputs from the code system. White box testing refers to software testing when the internal structure or implementation...
