 * Get a `Symbol.iterator` from an iterable or a `Symbol.asyncIterator` from an

 * @category Asynchronous Common
 * @example
 * ```typescript
 * const iterator = getIterator([1, 2, 3]);
 * iterator.next(); // { value: 1, done: false }
 * iterator.next(); // { value: 2, done: false }
 * iterator.next(); // { value: 3, done: false }
 * iterator.next(); // { value: undefined, done: true }
 * ```
 * @param iterable Iterable to get the iterator from.
 * @returns Iterator instance.
