 * @description
 * Only the first `count` values yielded from the source iterable are

 * @parameter
 * count
 * The number of values to propagate through.

 * @returns
 * Operator<T, T>
 *
 * @throws
 * `RangeError` when the given `count` is not an integer or less than zero.
 *
 * @example
 * j.pipe(
 *   'jupiterate',
 *   j.takeFirst(7),
