/**
 * 判斷任一字串陣列vtar內元素，是否「等於」任一字串陣列vhas內元素
 *
 * Unit Test: {@link https://github.com/yuda-lyu/wsemi/blob/master/test/arrHas.test.mjs Github}
 * @memberOf wsemi
 * @param {String|Number|Object|Boolean|Array} vtar 輸入被查找的字串陣列或字串
 * @param {String|Number|Object|Boolean|Array} vhas 輸入查找字串陣列或字串
 * @returns {Boolean} 回傳判斷布林值
 * @example
 *
 * console.log(arrHas([1, 2, 3, '4', 5, 'abc'], 2))
 * // => true
 *
 * console.log(arrHas([1, 2, 3, '4', 5, 'abc'], 6))
 * // => false
 *
 * console.log(arrHas([1, 2, 3, '4', 5, 'abc'], [2]))
 * // => true
 *
 * console.log(arrHas([1, 2, 3, '4', 5, 'abc'], [6]))
 * // => false
 *
 * console.log(arrHas([1, 2, 3, '4', 5, 'abc'], ['4', 2]))
 * // => true
 *
 * console.log(arrHas([1, 2, 3, '4', 5, 'abc'], ['7', 6]))
 * // => false
 *
 * console.log(arrHas([1, true, 2, 3, '4', true, 5, 'abc'], true))
 * // => true
 *
 * console.log(arrHas([1, true, 2, 3, '4', true, 5, 'abc'], false))
 * // => false
 *
 * console.log(arrHas([1, true, 2, 3, '4', true, 5, 'abc'], [true]))
 * // => true
 *
 * console.log(arrHas([1, true, 2, 3, '4', true, 5, 'abc'], [false]))
 * // => false
 *
 * console.log(arrHas([1, 2, { x: 'xyz' }, 3, '4', 5, 'abc'], { x: 'xyz' }))
 * // => true
 *
 * console.log(arrHas([1, 2, { x: 'xyz' }, 3, '4', 5, 'abc'], { x: 'opqr' }))
 * // => false
 *
 * console.log(arrHas([1, 2, { x: 'xyz' }, 3, '4', 5, 'abc'], [{ x: 'xyz' }]))
 * // => true
 *
 * console.log(arrHas([1, 2, { x: 'xyz' }, 3, '4', 5, 'abc'], [{ x: 'opqr' }]))
