 The library is a continuous effort to implement LINQ using latest features of TypeScript and JavaScript languages (For [ES5](http://www.ecma-international.org/ecma-262/5.1/) compatible library look at [linq-es5](https://github.com/ENikS/LINQ/tree/linq-es5) branch). The library is implemented in TypeScript and transpiled into JavaScript. It is distributed as a native module. It utilizes latest [ECMAScript 2015](http://www.ecma-international.org/ecma-262/6.0/) language specification:  [Iterables](http://www.ecma-international.org/ecma-262/6.0/#sec-iterable-interface) ([ [System.iterator] ](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols)), generators ([function*](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function*)), [for of](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) loops. <br/> All relevant methods are implemented with [deferred execution](https://blogs.msdn.microsoft.com/charlie/2007/12/10/linq-and-deferred-execution/) so no unnecessary iterations are performed. 
 The code is backwards compatible with [linq-es5](https://github.com/ENikS/LINQ/tree/linq-es5) and [C#](https://msdn.microsoft.com/en-us/library/system.linq.enumerable.aspx) implementations.
