JavaScript Split around curly braces

Question

I have a string format inside of a string variable:

\"{0} Hello World {1}\"

I need to split it into something like this:

\"{0}\

You can just filter out the empty strings if you want:

var s = "{0} Hello World {1}";
s.split(/({\d+})/).filter(Boolean);

which returns

["{0}", " Hello World ", "{1}"]
