Javascript

JavsScript, which is much different than the programming language Java, is used to enable enhanced interactivity between a webpage and a user. JavaScript functions can reside in an HTML document and can be called upon to perform tasks related to information displayed in a single webpage. For example, a JavaScript function can be referenced to validate the spelling within an HTML form before the form is sent off for further processing by another file. When a mouse click is detected, the JavaScript function will perform its tasks without redirecting the user to a new page.
