/**
 * Splits a collection into two groups, the first of which contains elements the
 * `predicate` type guard passes, and the second one containing the rest.
 *
 * @param data - The items to split.
 * @param predicate - A function to execute for each element in the array. It
 * should return `true` to add the element to the first partition, and and
 * `false` to add the element to the other partition. A type-predicate can also
 * be used to narrow the result.
 * @returns A 2-tuple of arrays where the first array contains the elements that
 * passed the predicate, and the second array contains the elements that did
 * not. The items are in the same order as they were in the original array.
 * @signature
 *    R.partition(data, predicate)
 * @example
 *    R.partition(
 *      ['one', 'two', 'forty two'],
 *      x => x.length === 3,
 *    ); // => [['one', 'two'], ['forty two']]
