var foo = function() {
  return 2;
}

var x = foo;

var y = foo();

// now x is a reference to the foo function
// whereas with y we called (or "invoked") foo, meaning y is set to foo's return value, 2.

Often I jump from Vim -> Command Line by backgrounding Vim with Ctrl-Z, doing my CLI stuff, and then going back to Vim with vi (which is just aliased to vim).

Sometimes though, I'll forget about my backgrounded Vim, and end up having another Vim process running.

How can I make my vi alias work such that:

• if there is a Vim process backgrounded, just foreground into that
• if there is not, load up vim as normal.

Thanks in advance!

I'd like to write a small shell script that takes the output of the `jobs` command, which looks like so:

[1]  - suspended  vim
[2]  + suspended  less foo.txt

And have it return a string like:

(1:vim 2:less foo.txt)

So I can add that to my PROMPT.

// I have this code for downloading a URL to a file
var stream = request(url).pipe(fs.createWriteStream(fileDestination))

// I can bind to "close" for when the file is completely downloaded, which works fine
stream.on("close", function() {...});

// is there an event I can bind to that will be fired whenever data is receieved (so not that the file is 100% done, but that a bit more of the file has been downloaded?

stream.on("???", function() {...});
