The Visual Studio Code shell is built on GitHub's Electron Shell, but the editor is a new and improved version of our own Monaco editor, which we use on Azure Websites, Visual Studio Online, and a number of other web sites, and in the F12 Tools in Internet Explorer.
It'll be interesting to see what the performance is like, since this has been a recurring problem with web-tech based applications (especially editors like Atom and Brackets).
Actually seems to work better than Atom or Brackets so far... I found both to be intolerable pretty quickly... this, I'll be continuing with for a couple days, I like the UI better than sublimetext so far.
I don't really understand the sentiment that you have expressed in your aside. If they deliver an interesting and/or useful product, why not reward them with credit?
removed it... I just don't like when I sound like a company shill. In this case imho the editor itself actually runs than my trials with brackets and atom... The startup time is actually tolerable, and the editing seems to work a little better too. A few days will determine if I go back to sublime again.
