linqscript

C# alike List in Javascript. Simple lightweight lambda syntax library for Typescript, extending Array.

No jQuery required! Unit tested.

Typescript arrow functions allows us, to use lambda syntax, which makes this easy to use.

This library extends the native Array. Use full advantage of an Array, extended with this methods. Works with Angular.

import { List } from 'linqscript';

USAGE:

var fruits = new List<string>();
fruits.Add("apple");
fruits.Add("banana");
 
var fruit = fruits.Where(x => x === "apple").First();

You can use of course more complex objects:

enum Color {
    Green,
    Red
}
 
class Fruits {
    public Name: string;
    public Color: Color;
}
 
var fruits = new List<Fruits>();
var apple = new Fruit();
apple.Color = Color.Green;
apple.Name = "Apple";
fruits.Add(apple);
 
var redApple = new Fruit();
redApple.Color = Color.Red;
redApple.Name = "Apple";
fruits.Add(redApple);
 
var kiwi = new Fruit();
kiwi.Color = Color.Green;
kiwi.Name = "Kiwi";
fruits.Add(kiwi);
 
fruits.Where(x => x.Color === Color.Green);

Output:
{
    "Fruits": [{
        "Name": "Kiwi",
        "Color": 1
    }, {
        "Name": "Apple",
        "Color": 1
    }]
}

fruits.Select(x => x.Color);

{
    "Color": [
        "Green",
        "Red"
    ]
}

fruits.Distinct(x => x.Name)

{
    "Name": [
        "Apple",
        "Kiwi"
    ]
}

List.Range(3, 10)
 
[3,4,5,6,7,8,9,10,11,12] // starting at 3, generates 10 numbers

var numbersToSum = new List<number>();
 
numbersToSum.Add(1);
numbersToSum.Add("2"); // will be converted
numbersToSum.Add(3);
numbersToSum.Add(5);
numbersToSum.Add("eight"); // will be ignored
numbersToSum.Add(8);
numbersToSum.Add(13);
 
var sum = numbersToSum.Sum(); // 32
 
var sumPlusOne = numbersToSum.Sum(x => x+1); // 38 -> use delegate to manipulate.
