: Does Spartan/Edge from Windows 10 use the same rendering engine with IE11? I decided to test the website I'm working on now in older versions of IE (such as IE 6, 7, 8) using the IE Developer

@Connie744

When I first read about this, it seemed to me, too, that Microsoft might actually be getting their act together and producing a responsible browser but didn't understand how they could use the same internal engines, as noted by @ivxenog , to accomplish a "new" browser. After more study, I realized that Microsoft is only taking IE and removing the old, legacy "cruft" and rebranding it as "Edge". Any new features, properties, elements, functionality are only items that would have made their way into future versions of IE anyway.

One method to find this out is the preponderance of footnotes in caniuse.com which state "Under consideration" or not implemented for Edge in the same quantity or history as for IE.

My point then is, the only difference between IE and Edge is that Edge will not contain support for remnants of old IE and old Windows needs and remains, essentially, IE as it is today: not very good: html6test.com/results/desktop.html

Spartan is still going to use Microsoft's Chakra JavaScript engine and
Microsoft's Trident rendering engine (not WebKit or gecko), Sources say.

So it is the same engine polished a little. Nothing fancy.
