Draw Star Using Web Application In TypeScript

Draw Star Using Web Application In TypeScript 

 
In this article, we draw a star in a web application in TypeScript.
 
First, we download some files in the following attachment:
  1. Kinect.d.ts
  2. Kinectic.min.js
These files are added to the project then use the following procedure.
 
Step 1
 
Open Visual Studio 2012 and click "File" -> "New" -> "Project...". A window is opened. In this window, click "HTML Application for TypeScript" under Visual C#.
 
Give the name of your application as "Draw_Star" and then click "Ok".
 
Step 2
 
After this session the project has been created; a new window is opened on the right side. This window is called the Solution Explorer. The Solution Explorer contains the ts file, js file, and CSS file and aspx page.
