Lotide is mini clone of the Lodash (https://lodash.com) library for learning JavaScript. What is Lodash? Lodash is a library that makes JavaScript easier by taking the hassle out of working with arrays, numbers, objects, strings, etc.

const middle = function (array) {
  if (array.length === 1 || array.length === 2) {
    return [];
  } else if (array.length % 2 === 0) {
    return array.splice(Math.floor((array.length - 1) / 2), 2);
  } else if (array.length % 2 !== 0) {
    return array.splice(Math.floor((array.length - 1) / 2), 1);
  } else {
    return [];
  }
};

module.exports = middle;
