How to Fix JavaScript Errors

JavaScript is an application that allows your computer to be able to run various media and audio and video files, as well as flash animations. JavaScript is common with a lot of different kinds of websites, and there are a lot of websites and applications that require it to view and use different programs and features. One of the most popular uses of JavaScript is used on gaming sites that use flash animations and interaction from the computer users.

You probably have used JavaScript often and have versions of it on your computer. There are times when JavaScript errors occur and there are reasons why these errors happen on your computer. One common reason that JavaScript errors occur is because the version of JavaScript that you are attempting to use is no longer able to run a program or open a file, or the file that you are trying to open is not compatible with the version of JavaScript that is on your computer. Most websites use the most recent version of JavaScript available, especially those that are updated regularly and have a lot of interaction from users.

When you see JavaScript errors and are not able to open a file or use a feature on a website, you may be instructed to verify what version of JavaScript you are running and see if it is the same as the version that the website is using. One way that you can fix JavaScript errors is to download the newest version of the JavaScript application and replace the older versions that are currently on your computer. It is important to keep in mind that the older versions on your computer, are not always automatically deleted or replaced when you download the newer versions, so you may need to manually go into your system folder and delete the older versions that are not working properly and then download and install the correct and most current version of JavaScript on your computer.

Another good tip to deal with JavaScript errors and to help prevent them from occurring is to do maintenance and clean up to your Windows Registry on a regular basis. This can help you make sure that your computer is working to its best ability and it can help get rid of potential problems on your computer. Your Windows Registry houses very important files that are necessary to help your computer and operating system run so it is important that you make sure that these files are not corrupt or damaged.

Be careful when you are on the Internet as to the websites that you go to and the files or programs that you download, many of these can be harmful to your computer, and you may get a virus or bug on your computer without being aware of it. Always make sure you are entering secure websites and downloading secure files to help make sure there are no viruses that will damage the files on your computer.
