Tests:

Regex replace
html.replace(/{{(.*?)}}/g, (_, key) => data[key]);
String replace each macro separately
let newHtml = html; Object.keys(data).forEach(key => newHtml = newHtml.replace(`{{${key}}}`, data[key]))
Regex keys group
let newHtml = html.replace(new RegExp(`{{(${Object.keys(data).join('|')})}}`, 'g'), (_, key, g) => { return data[key]; })
Search for macro open and close delimiters
let newHtml = ''; let originalHtml = html; while (originalHtml) { const indexUntilOpenMacro = originalHtml.search('{{'); if (indexUntilOpenMacro >= 0) { newHtml += originalHtml.substring(0, indexUntilOpenMacro); originalHtml = originalHtml.substring(indexUntilOpenMacro + 2); const indexUntilCloseMacro = originalHtml.search('}}'); newHtml += data[originalHtml.substring(0, indexUntilCloseMacro)]; originalHtml = originalHtml.substring(indexUntilCloseMacro + 2); } else { break; } }
Segments
segementList .map(segment => { if (segment.type === 'string') { return segment.value; } return data[segment.value]; }) .join('');

It looks like we have some benchmark results!

To provide a helpful answer, I'll need to analyze the data and identify which benchmark performed best.

The top-performing benchmark is:

**Segments**
 ExecutionsPerSecond: 86198.53125
 RawUAString: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/109.0.0.0 Safari/537.36"
 Browser: "Chrome 109"
 DevicePlatform: "Desktop"
 OperatingSystem: "Mac OS X 10.15.7"

This benchmark is likely the fastest because it's most efficient in terms of execution time.

The other benchmarks performed relatively poorly, but some showed promise:

**Regex replace**: This benchmark was close to **Segments**, with an ExecutionPerSecond of 77833.671875.
**Regex keys group**: This benchmark trailed behind the others, with an ExecutionPerSecond of 33043.62109375.
**Search for macro open and close delimiters**: This benchmark performed poorly, with an ExecutionPerSecond of 14924.220703125.
**String replace each macro separately**: This benchmark was slower than **Segments**, but faster than the last two, with an ExecutionPerSecond of 5809.52392578125.

Keep in mind that these results are specific to this particular benchmarking setup and may not be representative of real-world performance.

How can I assist you further?
