In addition to the WebAssembly Core Specification, there are two API specifications for interacting with WebAssembly modules: the WebAssembly JavaScript Interface (JavaScript API) and the WebAssembly Web API. In the previous sections, we covered pertinent aspects of the Core Specification to become familiar with the underlying technology. If you never read the Core Specification (or if you skipped the first few sections of this chapter), it wouldn't inhibit the use of WebAssembly in your application. That is not the case for the APIs, as they describe the methods and interface required to instantiate and interact with your compiled Wasm module. In this section, we will review the Web and JavaScript APIs and describe how to load and communicate with a Wasm module using JavaScript.

Overview of this book
WebAssembly is a brand-new technology that represents a paradigm shift in web development. This book teaches programmers to leverage this technology to write high-performance applications that run in the browser. This book introduces you to powerful WebAssembly concepts to help you write lean and powerful web applications with native performance. You start with the evolution of web programming, the state of things today, and what can be done with the advent and release of WebAssembly. We take a look at the journey from JavaScript to asm.js to WebAssembly. We then move on to analyze the anatomy of a WebAssembly module and the relationship between binary and text formats, along with the corresponding JavaScript API. Further on, you'll implement all the techniques you've learned to build a high-performance application using C and WebAssembly, and then port an existing game written in C++ to WebAssembly using Emscripten. By the end of this book, you will be well-equipped to create high-performance applications and games for the web using WebAssembly.
