JavaScript is a programming language and platform that allows users to take advantage of a wide range of functions and commands that other platforms do not provide. For example, JavaScript allows websites to run interactive menus, flash-based video games, and high quality interactive videos. However, while JavaScript may be used on a website, the viewer’s browser may not have JavaScript enabled, which may prevent him/her from seeing and using all of the components that the website has to offer.
Applications
As mentioned before, JavaScript can be used to provide websites with additional features that HTML and CSS do not, such as interactive menus and videos. Likewise, JavaScript can be used to provide interactivity to logos and other image based content.
How to Enable/Disable JavaScript
Although JavaScript should be enabled by default on any browser, JavaScript may become disabled accidentally or if the user recently changed browsers or modified the security settings. In order to enable or disable JavaScript, Internet Explorer users should:
1) Open the Tools Menu and select “Internet Options.”
2) Select the Security tab, click the Custom Level button, and scroll down to Scripting of Java Applets.
3) Select Enable or Disable, click OK, then click OK on Internet Options.
In order to enable or disable JavaScript, Firefox users should:
1) Click the Tools or Firefox button.
2) Click Options.
3) Select the Content tab.
4) Check or uncheck the “Enable JavaScript” checkbox then click OK.
