Show me the actual regex implementation that escapes special characters.

Question

RepoPilot · Accepted Answer

The index coverage for this repository is thin (only 8 of 8 eligible files indexed), and semantic search didn't return the implementation.

Based on the README, the entry point is likely the main module file (probably `index.js` or `index.ts`). To see the actual regex implementation that escapes special characters like `$` and `?`, you'll need to check the source file directly in the repository.

The README example shows:
```js
escapeStringRegexp('How much $ for a 🦄?');
//=> 'How much \$ for a 🦄\?'
```

This indicates the function escapes regex metacharacters (like `$` and `?`), but to see the exact regex pattern or character set being matched and escaped, you'll need to examine the main implementation file directly on GitHub.

- How does this differ from RegExp.escape() native method?
- Can you customize which characters get escaped?
