Can my JavaScript programs run on both Netscape and Internet Explorer browsers?
Unfortunately, not necessarily. JavaScript was created by Netscape, so it is most compatible with Netscape. Internet Explorer 4.x supports 99% of what JavaScript has to offer, although IE 3.x is not quite as adorable. A good rule to follow is to always test your codes using both browsers before uploading it onto the internet. You will be surprised how many websites fail to do this, annoying surfers and not even realizing that their scripts are going haywire behind their backs!
