如何在 MongoDB Shell 中定义别名？

Object.defineProperty(this, 'yourFunctionName', {
   get: function() {
      yourStatement1,
      .
      .

      return N
   },
   enumerable: true,
   configurable: true
});

var anyAliasName=yourFunctionName;

> Object.defineProperty(this, 'displayMessageDemo', {
...   get: function() {
...      return "Hello MongoDB"
...   },
...   enumerable: true,
...   configurable: true
... });

> var myMessage = displayMessageDemo;

> myMessage;

Hello MongoDB
