/**
 * #### Async Map
 *
 * Maps an array asynchronously
 *
 * * * *
 * Example:
 * ```typescript
 * import { asyncMap } "@thalesrc/js-utils/array";
 *
 * const array = [1, 2, 3];
 *
 * asyncMap(array, async value => {
 *  return await addOneAfterASecond(value);
 * }).then(result => {
 *  console.log(result); // [2, 3, 4]
 * });
 * ```
 *
 * Example as Array Prototype:
 * ```typescript
 * import "@thalesrc/js-utils/array/proto/async-map";
 *
 * const array = [1, 2, 3];
 *
 * const result = await array.asyncMap(async value => await addOneAfterASecond(value));
 * // [2, 3, 4]
 * ```
 * * * *
 * @param array Array to map
 * @param mapper Callback async function to map the array
 * @return A promise contains asynchronusly mapped array result
