      About the Author

      Preface

      The first part focuses on JavaScript basics. Covering topics like variables, functions, and conditionals. We also cover loops and closures too.

      Then in part two, we cover the core of JavaScript. Objects, Arrays, Type Conversion, Strings, and Numbers. Also, we review arrow functions that can be confusing syntax. The spread and rest operators are powerful to use.

      The third part gets to the advanced topics. For instance, the execution context and call stack are important to understand. Similarly, variable scope and the scope chain can help you know when you can and can’t use a variable.

      Overall, this book gives you are clear picture of the strength of JavaScript. It has evolved quite a bit over the many years of use. Starting quite small and growing into a more complete language.

      JavaScript Basics

      In part three, we start with the basics of JavaScript. We code some fundamental aspects to help you understand how to get around.

      Starting out with JavaScript

      I have a confession. JavaScript and I started badly. My first foray was for form validation. I would cuss about its existence.

      As luck would have after being reintroduced to it I began to respect it. Over the years it has grown into a powerful language.

      JavaScript

      With its humble beginnings, JavaScript has evolved into a modern programming language. From the browser to the server it can handle almost everything. Node.js gives it a powerful framework on the server side.

      Mozilla created it and here is how they define it. JavaScript is a lightweight interpreted programming language with first-class functions. That is a mouthful!

      Code

      Let’s look at some basic code. It is an HTML file displaying some JavaScript. Save this code to your local machine.

       

          JavaScript example code
