How to Check for Javascript Enabled

Javascript is a client-side programming language that is used on websites. Javascript is turned on by default when you install Firefox or Internet Explorer. Javascript is used for some malicious activity on websites that host malware, so some users prefer to disable Javascript for better security on their machine. You can disable and enable Javascript in the Web browser's settings. To check if Javascript is enabled, you simply need to view the browser's properties.
