require.js meets ES6 Promises

required.js

var required = function(name) {
      name = name.toString();
      return new Promise(function(resolve, reject) {
          require([name], function(module) {
            resolve(module);
          },
          function(err){
            reject(err);
          });
      });
    };
    
    //usage
    required("./test")
      .then(console.log.bind(console, "success:"))
      .catch(console.log.bind(console, "error:"));
