LinqTS

Native LINQ for Typesctipt
Version: alpha-0.28
License: MIT License

Features

• 28 LINQ methods
• implemented IEnumerator for javasctipt Array and Object
• maximum lazy evaluation
• only Typesctipt (maximum type-safety)
• fully tested (QUnit with d.ts)

Usage

var array = [2, 4, 6];
var enumerable = new EnumerableArray(array)
  .where(item => item > 5);
console.log(enumerable.count()); // 1

Supported methods (Enumerable<T>)

• all(predicate: (item: T) => boolean): boolean
• any(predicate: (item: T) => boolean): boolean
• average(selector: (item: T) => number): number
• cast<U>(type: IType<U>, strict: boolean = false): Enumerable<U>
• concat(secondEnumerable: Enumerable<T>): Enumerable<T>
• count(): number
• defaultIfEmpty(defaultValue: T = null): Enumerable<T>
• elementAt(index: number): T
• elementAtOrDefault(index: number, defaultValue: T = null): T
• empty<T>(): Enumerable<T>
• first(predicate: (item: T) => boolean = () => true): T
