How to Activate Java Script

To appear less static, websites rely on technologies like Java Script to provide immediate and intelligent interaction, or present animation and other visual effects. In fact, some websites may not display correctly if Java Script--sometimes used as a synonym for ECMAScript or JScript--has been disabled within your Web browser. Java Script is usually enabled by default, but if you need to activate Java Script manually, it will involve several steps that vary between brands of Web browsers. After you attempt to activate Java Script, you can also run a simple test to ensure you were successful.
