There are four browsers that are considered modern browsers. These are Edge, Chrome, Firefox, and Safari. These browsers uphold the latest in standards and are being actively developed. We will take a look at how each is developing and some of their unique features.
Internet Explorer is getting close to the end of its life cycle. The only development that will be happening with the browser is critical security fixes. New applications should try to deprecate this browser, but if there is a client base still utilizing it, then we may need to develop for it. We will not be focusing on polyfills for it in this book.
