Hmm I see your problem now. So the reason it wasn't working for you is because maybe you were doing this:

var wait = require('waitjs');

When your suppose to do this:

require('waitjs');

In node, var root = this; means var root = global; and in the browser it means var root = window;. So wait is added to the global object in node, the module doesn't returns anything. Also the tests are not passing so I'm gonna close the PR for now.

Not global, exports. Two different things.
