Compare async iteration on nested & flat arrays

Benchmark created on

Setup

function processAsync(item) {
  return new Promise(function(resolve) {
    setTimeout(
      resolve,
      Math.random() * 1000
    );
  });
}

const nestedArr = [["a", "b", "c"], ["d", "e", "f"], ["g", "h", "i"]];
const flatArr = ["a", "b", "c", "d", "e", "f", "g", "h", "i"];

  return Promise.all(arr.map(processAsync));
})).then(data => {
  console.log(data);
});
ready
flattened array with loop
Promise.all(flatArr.map(processAsync)).then(data => {
