Summary

During this lesson, you’ve learned what web scripting is and what JavaScript is. You’ve also learned how to insert a script into an HTML document or refer to an external JavaScript file, what sorts of things JavaScript can do, and how JavaScript differs from other web languages. You also wrote a simple JavaScript program and tested it using a web browser. You also learned how to modify and test scripts, and you saw what happens when a JavaScript program runs into an error.

In the process of writing this script, you have used some of JavaScript’s basic features: variables, the document.write statement, and functions for working with dates and times.

Now that you’ve learned a bit of JavaScript syntax, you’re ready to continue on to learn all sorts of things about web development before settling in to writing interactive websites using client-side scripting.

On rare occasions it is necessary to send out a strictly service related announcement. For instance, if our service is temporarily suspended for maintenance we might send users an email. Generally, users may not opt-out of these communications, though they can deactivate their account information. However, these communications are not promotional in nature.
