javascript - Property names with spaces in object literals

I'm just wondering, with the "one", "two", "three" stuff, could there be a space? So instead of "one" it could be "one meow"?

var meow    = { one:        function (t) { return "a"; },
                two:        function (t) { return "b"; },
                three:      function (t) { return "c"; }
              };

Sure, there can be spaces in property names, but then you have to enclose them in ":

var meow    = {
            "one meow": function (t) { return "a"; },
            two:        function (t) { return "b"; },
            three:      function (t) { return "c"; }
            };

When you want to access that property later, use the bracket syntax:

console.log( meow["one meow"]() );
