parse JSON string and keep the props in alphabetic order

json_alphabetic.js

function sortObjectAlphabetically(obj) {
  if (typeof obj !== 'object' || obj === null) {
    // Base case: obj is not an object, or is null
    return obj;
  }

  if (Array.isArray(obj)) {
    // If obj is an array, recursively sort its elements
    return obj.map((element) => sortObjectAlphabetically(element));
  }

  // If obj is an object, recursively sort its properties
  const sortedObject = {};
  Object.keys(obj).sort().forEach((key) => {
    sortedObject[key] = sortObjectAlphabetically(obj[key]);
  });

  return sortedObject;
}

// Your JSON string
const jsonString = '{"c": 3, "a": 1, "b": {"d": 4, "e": 5}}';

// Parse JSON string into a JavaScript object
const jsonObject = JSON.parse(jsonString);

// Sort the entire object alphabetically
const sortedObject = sortObjectAlphabetically(jsonObject);

// Display the result
console.log(sortedObject);
