How to use the can-connect/helpers/.each function in can-connect

// Check if the same fixture was previously added, if so, we remove it
		// from our array of fixture overwrites.
		var index = find(settings, !! fixture);
		if (index > -1) {
			overwrites.splice(index, 1);
		}
		if (fixture == null) {
			return;
		}
		settings.fixture = fixture;
		overwrites.push(settings);
		// If a fixture isn't provided, we assume that settings is
		// an array of fixtures, and we should iterate over it, and set up
		// the new fixtures.
	} else {
		helpers.each(settings, function (fixture, url) {
			$fixture(url, fixture);
		});
	}
};
var replacer =  /\{([^\}]+)\}/g;
