Yea, I just looked and Brackets apparently just uses the
filesystem.
I didn't mean a "virtual server" (whatever that is!)
I just meant you don't need a "grownup" server
like IIS. It's probably overkill, but if it comes bundled in VS,
so be it.
Most other modern-ish HTML code editors have a real (but
small/simple) server that typically runs on localhost:8080 by default.
(Or perhaps installable as a plugin.)
If you have node/npm or Ruby/RubyGems installed, there are many
choices that can be installed in an instant.
Just putting this out there for others. You don't have to
hassle with installing and configuring a complicated server like IIS
or Apache. (Unless you need to write server-side code.) There is no
excuse for working from the filesystem!
