 * Gets an aggregated result of async operation for each element of given Array

 * @param {Array<T>} arr source array

 * @throws {TypeError} getAsyncMap: callback must be a function

 * @example
 * // How to call API for each element of an array and return a result?
 * const myAPIFn = (item, index, arr) => Promise.resolve("success" + item);
 * const array = [ 1, 2, 3 ];
 * const result = await getAsyncMap(array, myAPIFn);

 * @example
 * // Fetch user profiles for every ID in parallel
 * const users = await getAsyncMap(userIds, async (id) => {
