JavaScript is a language that is used in conjunction with HTML. It
is embedded into an HTML script to create dynamic web page content.
For example, it allows a software coder to control what appears on a web
page based on input from the user or other variables.
JavaScript is the most widely used scripting language on the net and was
designed specifically for generating dynamic web pages. Because if its
widespread use and the ever expanding popularity of the Internet in our
economy, a good knowledge of JavaScript is important for web developers and
all software coders.
Even if an application developer doesn't need to write JavaScript, he or
she will sometimes have a need to invoke a JavaScript module written
by someone else.
