Microsoft went on to explain
how modern browsers transform JavaScript to native code, but «enabling Just - in - Time (JIT) compilers to work with ACG enabled is a non-trivial engineering task.»
Or, pushes to evolve the standard and what it is capable of doing will lead to features being inconsistently supported, as is the case with HTML5 and
modern browsers, and we'll forever have our heads under the bonnet trying to figure out
how to make the damn thing work.
During the announcement, which you can watch here, Microsoft spent a ton of time talking about
how Cortana is integrated into the operating system,
how Modern apps use the same code across desktops, tablets, phones, and even Xbox,
how the new Spartan web
browser lets you write on the screen to annotate the web, and the entirely new holographic interface (requires the HoloLens goggles).
