# fromit

Linq style (like in c#) using generators

```sh

npm install fromit

```

Or use directly

```html

```

```ts

import { from } from "fromit";

const list = new Set([1, 2, 3]);

expect(

  from(list)

    .filter(x => x > 2)

    .first()

).toBe(3);

const a = [1, 2, 3];

const b = [3, 4, 5];

let r = from(a).intersect(b);

expect(r.count()).toBe(1);

// speed up array functions

const slow = [...from(1000)].map(x=> x + 1).find(x=> x == 4);

const fast = from(1000).map(x=> x + 1).find(x => x == 4);

// used with async await

async function* generator() {

  yield 1;

  yield 2;

  yield 3;

}

async function promise(): Promise {

  return [1, 2, 3];

}

const result1 = from(generator());

const result2 = from(promise());

expect(await result1.toArray()).toStrictEqual(await result2.toArray());

```
