Module: kongUtilArray

Functions in this file could be assigned to Array.prototype, and then you can use them as methods of an array. Assign what you want by yourself or call extendArrayPrototype() to add them all.

These functions are designed to run sequentially. If you want to run every async functions at the same time, consider static methods of Promise, such as all, any, race, and allSettled.

Note: to make this work, don't use arrow functions here.

Examples
// sequentially fetch resources and then resolves to responses.
    Array.prototype.mapAsync = kongUtilArray.mapAsync; // run once
    [url1, url2].mapAsync(fetch);
// same as above
    kongUtilArray.mapAsync(fetch, [url1, url2])
