Summary

This chapter’s goal has been to provide a glimpse of JavaScript and a little understanding of what it can do. JavaScript ranges from very simple but useful applications to very complex scripts that handle complex tasks. Don’t expect to learn the language all at once, but do begin to think about designs that can be aided by the inclusion of JavaScript in your web pages. Include interactive elements in your pages using JavaScript so that the viewer is engaged in the page rather than a passive audience. Like all languages, the more you use it, the easier it becomes to apply in your web pages. So, start using the language right away.

JavaScript is interpreted by your browser, and while different browsers can require different scripting strategies, most JavaScript follows the ECMA-262 standard. However, be aware that some nagging differences exist. In later chapters, you will be prepared with strategies for dealing with these differences.
