@nknahom/lotide/map.js

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 map = (array, callback) => {
  const results = [];
  for (let item of array) {
    results.push(callback(item));
  }
  return results;
};

module.exports = map;
