Promise Serial

Examples

const waitFor =
  async (ms: number) =>
    new Promise(resolve => setTimeout(resolve, ms));

const array = [5, 3, 1];
const result = await map(array, async (value, i) => {
  await waitFor(value * 100);
  return {v: value, i};
}); // => {v: 5, i: 0}, {v: 3, i: 1}, {v: 1, i: 2}

or 

const array = [5, 3, 1];
const wrapper = wrap(array);
const result = await wrapper.map(async (value, i) => {
  await waitFor(value * 100);
  return {v: value, i};
}); // => {v: 5, i: 0}, {v: 3, i: 1}, {v: 1, i: 2}

Functions
