018 —2633. Convert Object to JSON String.js

/**

 * @return {string}

var jsonStringify = function(object) {
    if (object === null) {
    return 'null';
  }

  if (Array.isArray(object)) {
    const elements = object.map((element) => jsonStringify(element));
    return `[${elements.join(',')}]`;
  }

  if (typeof object === 'object') {
    const keys = Object.keys(object);
    const keyValuePairs = keys.map((key) => `"${key}":${jsonStringify(object[key])}`);
    return `{${keyValuePairs.join(',')}}`;
  }

  if (typeof object === 'string') {
    return `"${object}"`;

  return String(object);

// SOLUTION 2:
// /**
//  * @param {any} object
//  * @return {string}
//  */
// var jsonStringify = function(object) {
//     return JSON.stringify(object)
