HTML Script
HTML allows programmers to include scripts in HTML Page. JavaScript which is a client side scripting language can be included in HTML Page.

Java script are used to make html pages dynamic. It can be used for image manipulation and form validation. Html provides flexibility to include java script code.

Sometimes script may be disabled in user browsers or the browser may not support scripts. To handle such cases html provides <noscript> tag to provide an alternative content for users. <noscript> Element can contain all elements that are supported by html. The contents inside <noscript> tag will be displayed only if the browser dose not support scripting or script is disabled in the browser.
