Based on the provided information, it appears that we are dealing with two benchmarking tests for sorting dates using Moment.js. The raw data includes an array of date objects and their corresponding HTML code.

To answer your question without any further context or clarification, I will provide a general outline of how to approach this problem:

1.  **Sort the Date Array**:
    *   Use JavaScript's built-in `sort()` method to sort the `momentDates` array in ascending order.
2.  **Memoization**:
    *   To implement memoization, we can create a cache object to store the results of previously computed values.
    *   We will then check if the result is already cached before computing it again.
3.  **Compare Benchmark Results**:
    *   Compare the execution times for both sorting methods (with and without memoization) using the provided benchmark data.

Here's a basic example in JavaScript that demonstrates how to sort the date array with and without memoization:

```javascript
// Define the raw dates array
const rawDates = [
  { startDate: '2020-02-01', endDate: '2020-02-29' },
  // ... other date objects ...
];

// Moment.js library for date formatting and sorting
const moment = require('moment');

// Function to sort dates without memoization
function sortMomentDatesWithoutMemoization() {
  return rawDates.sort((a, b) => a.startDate.localeCompare(b.startDate));
}

// Function to sort dates with memoization
function sortMomentDatesWithMemoization() {
  const cache = {};
  return function (array) {
    if (!cache[array]) {
      cache[array] = array.sort((a, b) => a.startDate.localeCompare(b.startDate));
    }
    return cache[array];
  };
}

// Example usage:
const sortedDatesNoMemo = sortMomentDatesWithoutMemoization();
const sortedDatesWithMemo = sortMomentDatesWithMemoization();

console.log('Sorted dates without memoization:');
console.log(sortedDatesNoMemo);

console.log('Sorted dates with memoization:');
console.log(sortedDatesWithMemo);
```

This code snippet demonstrates how to create a sorting function that uses memoization. It can be further refined and integrated into the original benchmarking test to compare the execution times of both methods.
