JavaScript is the lingua franca of the web, but before using it to create dynamic websites, you need to understand how it works. In this workshop trainer and developer Joe Chellman explores the syntax behind the JavaScript language. He shows how to "speak" JavaScript by gaining an understanding of variables, types, objects, arrays, operators, control structures, loops, and functions, through a series of hands-on examples that put these ideas into action. After completing this course, most developers will understand the core syntax of JavaScript and how this scripting language works to build powerful and complex functionality on the web.

Topics include:
  • Enabling Firebug and web inspectors
  • Using a text editor
  • Declaring and assigning a variable
  • Booleans and the quest for truth
  • Working with objects and arrays
  • Using operators and control structures
  • Iterating with loops
  • Objects, references, and functions
  • Understanding variable scope

Welcome

- [Voiceover] Hi, I'm Joe Chellman. I'm a web developer and consultant, and also a trainer on various video to brain open source and content management system topics. I've been using JavaScript for around 12 years, so I not only teach on the topic, I use it daily to create websites and pages for my clients and myself. Back when I started creating webpages, HTML was the only language available and you had to code static sites page by page. Since that time, a lot has changed, including the growth of JavaScript, which is now literally almost everywhere on the web, powering some of the most popular and commonly used websites, and enabling pages to run smoothly on both regular sites and mobile apps.

As with any language, whether it's for computers or humans, a key to really grasping the power behind JavaScript is understanding its syntax. Luckily, it's not very complicated, but still has a lot of expressive power. This course will walk you through JavaScript's syntax basics, from understanding what each element is, to seeing it in action. We'll start of with variables, learning how to declare and assign them, and then running through numbers, strings, Booleans, objects, arrays, and much more. We'll then move on to exploring operators, both arithmetic and logical, and then seeing how conditionals work, and getting a solid feel for how to use loops.

Finally, we'll dive into understanding functions and how they not only fit into JavaScript, but how they're a little different from functions in many other popular programming languages. With the help of this course, you'll be able to start really understanding the core syntax of JavaScript and how the scripting language works to build powerful and complex functionality on the web. So, let's get started.
