High performance sequence engine in Javascript that optimizes execution of sequences in Immutable.js

and provides fast incremental processing of insert, update, and delete operations. Fully integrated with [DUXEN](https://applitopia.github.io/duxen).

See [http://applitopia.github.io/seqen](https://applitopia.github.io/seqen) for detailed documentation.

Installation

------------

```shell

npm install seqen

```

Example

------

```js

const cmp=(a,b)=>(a>b?1:a seq

  .filter((v, k) => (k % 2 == 1))

  .map((v) => v.toLowerCase())

  .sort((a, b): number => cmp(a, b))


const map = Map().withMutations((map) => {

  map.set(1, "Peter");

  map.set(2, "Xavier");

  map.set(3, "Alex");

  map.set(4, "David");

  map.set(5, "John");

});

const seqen = new Seqen(map, recipe);

const result1 = seqen.result().toIndexedSeq().toJS();

expect(result1).toEqual(["alex", "john", "peter"]);

```
