As we know, it’s very difficult to make the IDE to recognise the function of JavaScript, we called code intellisense, because JavaScript is weak language. So how to solve this problem. There is a way.
TSD is TypeScript Definition manager for DefinitelyTyped. It can search and install TypeScript definition files directly from repository. The TypeScript definition file actually is TypeScript file, and TypeScript is strong type language. So IDE can intellisense the code, like Java and C#.
TypeScipt is also like CoffeeScript, it can be compiled to JavaScript. It is developed by Microsoft company. To See the TypeScript, go to this official website.
