@ 2015/05/27Microsoft is pushing their new Edge browser (formerly Project Spartan) as the replacement for Internet Explorer 11. Back on May 5th, Microsoft opened up the Microsoft Edge Dev Blog and ever since then they have been bringing to light a lot of the changes that are coming with Edge. One of the first posts was detailing what has been changed with Edge as compared to Internet Explorer 11.
Edge is not a completely new browser. Internet Explorer was based on the Trident web rendering engine, and the Chakra ECMAscript engine, and these continue to be the basis of Edge as well. However Edge will not have any of the legacy compatibility requirements of Internet Explorer, which has allowed the company to strip out a lot of unnecessary code. According to Microsoft, over 220,000 lines of code have been removed to strip out the features that are no longer part of the modern web. This includes things like ActiveX extensions, Browser Helper Objects, IE Document Modes, Vector Markup Language, VBScript, and more. For a full listing, check out their blog post here. They obviously did not just stop at removing old code though, and over 300,000 new lines of code have been added for 49 new features and over 4000 interoperability fixes.
