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

parseListData: function( responseData ) {

			// call any base parseListData
			if(baseConnect.parseListData) {
			   responseData = baseConnect.parseListData.apply(this, arguments);

				responseData.data = helpers.getObject(prop, responseData);
				result = responseData;
				if(prop !== "data") {
					delete responseData[prop];
				}
				if(!isArray(result.data)) {
					throw new Error('Could not get any raw data while converting using .parseListData');
				}

			}
			var arr = [];
			for(var i =0 ; i < result.data.length; i++) {

module.exports = function(data){
	if(isArray(data)) {
