Web Api Versioning using Url Path

Why we need versioning in Api? Once a Web API service is made public, different client applications start using your Web API services.As the business grows and requirements change, we may have to change the services as well, but the changes to the services should be done in way that does not break any existing client applications. This is when Web API versioning helps.   There are many approaches about how should one implement the api versioning. My favorite is putting the versioning in the Url path.

What is Different Between Jquery & JavaScript?

JQuery is a framework for writing javascript tasks in a easier way. JQuery it is written in javascript. Also, I should mention that browsers parse only html and css files as also js scripts. Hence, all javascript frameworks (jQuery, AngularJS, etc) are written in javascript. They provide you the oportunity to write js code easier but under the hook they are all written in javascript. An example in order to understand why JQuery is easier. Say we have the following input element:- <input id="button1" type="button" value="clickMe"/ > Also say that we want when someone click on the button to have an alert box showing to the user a 'Hello' message.Then the code in javascipt would be:- document.getElemementById("button1").addEventListener('click', function(){     alert("Hello"); }); Using JQuery the above would be written as follows: $('#button1').click(function() {  alert(...

What is typescript & Its features ?

Define Typescript:- TypeScript (TS) is an open source programming language developed by Microsoft. Typescript is a superset of JavaScript which primarily provides optional static typing, classes and interfaces. What is the different static and dynamic typing? Static typing:- It's all about the variables. In statically typed program languages, if I create an integer, I have to tell the compiler that it is an integer and will always be an integer. Dynamic typing:- In dynamic languages, you don't specify the type and you can dynamically change the type. For example, to declare a variable in Javascript, you would type var bar; . If I then set it to an integer, it will work fine. bar = 5; . I can then even later set the same variable to a string, bar = "Hello World!"; and it will work fine! Hence the term dynamic. Before we start typescript lets show some ECMAScript 6 Features that help in typescript. 1.          ...
