Based on the provided benchmark result, it appears that the `replaceAll` function performs well in Chrome 118 on Windows.

To answer your question without seeing the code, I can provide some general insights:

1. **JavaScript performance**: The benchmark result shows that the `split + join` and `replaceAll` functions are executed at different speeds. This suggests that JavaScript performance is a significant factor in this benchmark.
2. **Browser performance**: Chrome 118 on Windows performs well in both tests, indicating good browser performance.
3. **String manipulation**: Both tests involve string manipulation, which can be computationally intensive. The `replaceAll` function might have an advantage over the `split + join` approach due to its optimized implementation.

However, without seeing the code, I couldn't provide a definitive answer on whether the `replaceAll` function is faster or slower than the `split + join` approach. If you'd like to discuss further or share the code, I'm here to help!
