/** 
 * Web browsers use URIs for the href attribute of the <a> tag and for bookmarks. The URI scheme, such as http:, file:, or ftp:, specifies the protocol and the format for the rest of the string.
 * Browsers also implement a prefix javascript: that to a parser is just like any other URI.
 * Internally, the browser sees that the specified protocol is javascript, treats the rest of the string as a JavaScript application which is then executed, and uses the resulting string as the new page.
 * 
 * The executing script has access to the current page, which it may inspect and change.
 * If the script returns an undefined type (rather than, for example, a string), the browser will not load a new page, with the result that the script simply runs against the current page content.
 * This permits changes such as in-place font size and color changes without a page reload.
