/**
 * Creates a slice of `array` with `n` elements taken from the end.
 *
 * @since 3.0.0
 * @category Array
 * @param {Array} array The array to query.
 * @param {number} [n=1] The number of elements to take.
 * @param- {Object} [guard] Enables use as an iteratee for methods like `map`.
 * @returns {Array} Returns the slice of `array`.
 * @example
 *
 * takeRight([1, 2, 3])
 * // => [3]
 *
 * takeRight([1, 2, 3], 2)
 * // => [2, 3]
 *
 * takeRight([1, 2, 3], 5)
 * // => [1, 2, 3]
 *
 * takeRight([1, 2, 3], 0)
 * // => []
