# lambda.js
Functional extension methods (inspired by LINQ .NET) on JavaScript arrays

THIS PACKAGE IS DEPRECATED!
Please switch to the array-x package (https://www.npmjs.com/package/array-x)



## Examples
```
require("lambda.js")(); // Note that, starting with version 2.0.0, the imported module function must be executed to extend the array type

var arr = [1, 2, 3, 4, 5, 6, 7];
arr.forAll((item) => console.log(item));
console.log(arr.select((item) => item * 10));
console.log(arr.where((item) => item > 4));
```
