Javascript code is not working in node?

Question

I wrote a code to solve this keyword issues in setTimeout() function. And tried to run it in node and it showed throw err; can't find module error. Then I tried to run it in a browser and it worked. I mean how to know when to test our code in nodejs and when not. This is my code

function person () {
    var firstName ;
    var _this_ = this;

    return {
        saveContext: function(context) {
        _this_ = context;
    },
        setName: function(name) {
        _this_.firstName = name;
    },
        getName: function() {
        console.log(_this_.firstName);
    }
  };
}

var employee1 = new person();
employee1.saveContext(employee1);

employee1.setName('Steve');
employee1.getName();

setTimeout(employee1.getName, 1000);

Works for me in both Node 4 and Node 6. I wouldn't, at all, recommend writing code like that, but it works. — T.J. Crowder

"Or how can I improve my code. " is too broad for SO. You might review the guidelines over at codereview and, if this is in keeping with them, post there. — T.J. Crowder

Please post the full error and the full relevant source code. We can't help you debug what we can't see. — Andy Ray

The "can't find module" error is thrown when:

You try running node on a non-existent file.
The file exists, but it's not in that directory.
You require a file which doesn't exist.

Make sure npm port is running using below command to overcome running again and again server.

nodemon entryfilename.js

Secondly , test using npm if installed properly in your root directory.
