Tests:

Build function
const buildData = () => makeExampleData(); for (let i = 0; i < 100; i += 1) { const newData = buildData(); }
New function, no cache
for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(makeExampleData()); const newData = new Function('json', `return json`)(json); }
New function, cached data
const data = makeExampleData(); for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(data); const newData = new Function('json', `return json`)(json); }
New function, cached stringify
const json = JSON.stringify(makeExampleData()); for (let i = 0; i < 100; i += 1) { const newData = new Function('json', `return json`)(json); }
JSON stringify & parse, no cache
for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(makeExampleData()); const newData = JSON.parse(json); }
JSON stringify & parse, cached data
const data = makeExampleData(); for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(data); const newData = JSON.parse(json); }
JSON stringify & parse, cached stringify
const json = JSON.stringify(makeExampleData()); for (let i = 0; i < 100; i += 1) { const newData = JSON.parse(json); }

LLMs can make mistakes. Check important info.

It seems like you're looking for insights from benchmark results.

Here are some observations and potential takeaways:

1. **Cache benefits**: The cached data tests show slower execution times compared to the non-cached data test, indicating that the caching mechanism is not providing significant performance gains in this case.
2. **Stringify & parse without caching**: This test has a relatively low execution time, suggesting that the overhead of JSON serialization and deserialization is manageable for most use cases.
3. **Build function vs new function**: The "Build function" and "New function, no cache" tests have similar execution times, while the corresponding cached data tests are slower. This suggests that building data from scratch can be more efficient than using cached data in certain scenarios.

To further optimize performance:

* Investigate why caching is not providing benefits in the cached data tests.
* Consider implementing a more effective caching mechanism or optimizing the data structure to reduce serialization overhead.
* Profile and test different approaches for building data, including both building from scratch and using cached data.
