javascript - How do I return this object, instead of logging it? -

-

I have a static site generator for which I listed all the available partial list in the template / partial 

  var partials = {'header': 'partials / header', // to ' ./templates/partials/header .html "Footer": 'partial / footer' // './templates/partials/footer.html'};

I have put this node script together: 

  'strict use'; / ** * Dependency * / var fs = Required ("FS"); Var Path = Requirement ("Path"); Var p = 'templates / partial'; / ** * Object with scanned folder and object partial * / fs.readdir (p, function, err, files) {var obj = {}; if (err) {err err;}; for (var i = 0; I & lt; files.length; i ++) {obj [path.basename (files [i], '.html')] = 'partial /' + files [i];}; console.log (obj); });

When it is executed with the root of the project, it is logged: 

  {footer: 'partial / footer html', header : 'Partial / header html'}

which is good, but I want to return it, do not log in. I have also come to know that what I have written is unlucky, so my question is, how do I return the item, and how do I strengthen it more?

You should provide a callback function: 

  function readfile ( Callback) {fs.readdir (p, function (error, files) {var obj = {}; if (mistake) {throw throw;}; (var i = 0; i

It will be used as follows: 

  readfiles (functions (files) {// doo dots with file here}});

The callback function allows IO to do asynchronously; It often provides a big speed for the code because IO does not need to wait to finish it. In this case, this is not very useful, but the callback pattern is very common in Node.js and hence its use here Have good practice to do

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
