Choosing Prebuilt Scripts

You don't need to learn JavaScript to be able to use it.

There are lots of places on the web where you can obtain JavaScripts that have already been written and where the author gives their permission for the script to be copied to be used on other sites. Some of these scripts have been recently written or updated and use all of the correct standard ways of doing things in JavaScript. Many of the scripts that you can find were written several years ago before the current standards were developed and were designed to run on browsers such as Internet Explorer 4. While these old scripts may still run on some more recent browsers there will certainly be lots of newer browsers where they will not work properly. With a few simple checks that anyone can carry out you can get a better idea of whether the prebuilt script that you have found is intended to run on modern browsers or whether it was written to run on browsers that date back to the twentieth century.
