If you are a newbie to Angular 2 then you can follow my below links . I am sure you will able to write the Angular 2 applications within 5 minutes. What is typescript ? http://whymysolutions.blogspot.com/2017/09/what-is-typescript.html Angular 2 project set up in Visual studio code and a Small Angular 2 application example. https://whymysolutions.blogspot.com/2018/09/angular2-application-in-visual-studio.html If you are comfortable with basic of Angular 2 then you can directly learn this article step by step. First we will describe the service creation and then we will use it in a small application. Step 1 : Create the service file     First we will create a file having the name as  m ydemoservice.service.ts .

base keyword is used to refer the Base class member . Base class is also called as Parent class and Super class as well. So when to use base Keyword. > To access the base class method which is overridden in child class . > If you want to access the base class constructor while creating the child class object . Lets explain it an example. Case-1 : public class PersonDetails {     protected string name = "John";     public virtual void GetInfo()     {         Console.WriteLine("MyName: {0}", name);     } } class EmployeeDetails : PersonDetails {     public string empid = "AA23";     public override void GetInfo()     {         base.GetInfo();         Console.WriteLine("Employee ID: {0}", empid);     } } class TestClass1 {     static void Main()     {         EmployeeDetails Emp = new EmployeeDetails();         Emp.GetInfo();     } } /* Output : MyName: John Employee ID: AA23 */ Case -2:

I was trying to upload a file in client side and sending back the data from the client to Web API controller by angular service . Step 1 : I was doing it by. (It was bot the complete code )   function saveFile(file, cb) {     var readerObj = new FileReader();     readerObj .readAsDataURL(file);     readerObj .onload = function () {         savedFileDataAsBase64Format(readerObj .result, file.name,cb);     };     readerObj .onerror = function (error) {         alert("Error in uploading the file.");     }; Step 2 :     This is my Web api controller action method.        [HttpPost]         [Route("api/FileInput/SaveBase64FileData/{fileName}")]         public void SaveBase64FileData(string fileName, [FromBody]string fileData)         {             byte[] bytes = Convert.FromBase64String(fileData);            // Write code what ever you want to do         } So from the first line of the actions method I was getting the mentioned error.

In this article we will discuss about the component that we are using angular2 application . A angular component mainly consist of three things. 1. Class 2. Template 3. Metadata. We will discuss it one by one . Lets first add a component through Visual studio code. Basically the component is created with .ts extensions and we keep the name as filename.component.ts  . Now we will discuss it one by one. 1. Class : Like other object oriented programming language we declare the class . class is declared with a name and having some property , method and constructor as well. 2. Template :  Template is nothing but an view part of the application . What ever we want to render in the screen that should be mentioned in the template section . Basically the template section contains the HTML content. 3. Metaddata :  Its a extra data used to decorate the angular class for behaving the class properly. Angular2 uses several entries for metadata like annotations, design : pa

1. What should be the output of the following code snippet. const arr = [1, 2, 3, 4]; for (var i = 0; i < arr.length; i++) {   setTimeout(function() {     console.log('Index: ' + i + ', element: ' + arr[i]);   }, 4000); } Output :  Index: 4 ,  element: undefined Explanation : Actually the setTimeout function will create a closure function which have access to the upper local variable i . So once the for loop gets executed the setTimeout function is get executed and the i value goes up . So within this 1 sec the i value goes upto 4 and the arr[4] value would be undefined .
