## Example

```javascript

import OnionStack from 'onion-stack';

const list = [];

const stack = new OnionStack(

    function* () {

        list.push(1);

        yield;

        list.push(2);

        yield;

        list.push(3);

    },

    async function* () {

        await delay(0.1);

        list.push(4);

        yield;

        list.push(5);

    },

    function () {

        list.push(6);

    }

);

stack.execute().then(() => console.log(list)); //  [1, 4, 6, 5, 2]
