 * Creates a shallow copy of a portion of a given array, filtered down to just
 * the elements from the given array that pass the test implemented by the

 *
 * @param data - The array to filter.
 * @param predicate - A function to execute for each element in the array. It
 * should return `true` to keep the element in the resulting array, and `false`
 * otherwise. A type-predicate can also be used to narrow the result.
 * @returns A shallow copy of the given array containing just the elements that
 * pass the test. If no elements pass the test, an empty array is returned.
 * @signature
 *    R.filter(data, predicate)
 * @example
 *    R.filter([1, 2, 3], x => x % 2 === 1) // => [1, 3]
