Sort JSON: Fix Unordered JSON Strings

There are two main methods to solve the problem of disorder in JSON strings.

1. Sort a JSON object using the `JSON.stringify()` method and a custom sorting function.

const jsonStr = JSON.stringify(jsonObj, (key, value) => {
  if (typeof value === 'object' && !Array.isArray(value)) {
    return Object.keys(value).sort().reduce((sorted, key) => {
      sorted[key] = value[key];
      return sorted;
    }, {});
  }
  return value;
});

This ensures that the key-value pairs in the generated JSON string are arranged in alphabetical order of keys.

1. Utilize a stable stringification method, such as the replacer function of JSON.stringify() or third-party libraries like fast-json-stable-stringify.

const fastJsonStringify = require('fast-json-stable-stringify');

const sortedJsonStr = fastJsonStringify(jsonObj);

This method ensures that the generated JSON strings will have consistent sorting results across different environments.
