How to read current record in a custom module in SuiteScript 2.0

define([‘N/currentRecord’], function(currentRecord) {

 return({
alertBox: function(){
var record = currentRecord.get();

var name = record.getValue({
fieldId: ‘custpage_name’,
})

alert(name);
}
 });

}

This simple module can be attached to suitelet or user event script and can be used by calling alertBox function directly.
