Javascript is a programming language that can be included on web pages to make them more interactive. When a user visits a webpage containing Javascript, the web browser executes (or runs) the script.  This means that websites can include programs running directly inside the browser rather than requiring the user to download and install an application on their computer.  When you encounter a Javascript error, it is likely your browser isn’t able to process the Javascript code. Most of the time, this is because of an outdated version of the software or browser.
