Show me the actual regex implementation that escapes special characters.

Unfortunately, the repository has minimal indexed code coverage (only 8 files indexed), and semantic search returned no results. The actual implementation code wasn't retrieved in the initial pass.

However, based on the README, the main entry point is likely the default export in the primary module file. The usage example shows:

import escapeStringRegexp from 'escape-string-regexp';

const escapedString = escapeStringRegexp('How much $ for a 🦄?');
//=> 'How much \\$ for a 🦄\\?'

To see the actual regex implementation that performs the escaping, you'll need to:

1. Check the main module files — likely index.js, index.ts, or index.mjs in the repository root
2. Look for a RegExp pattern that matches special characters that need escaping (typically characters like .*+?^${}()|[]\)

The README indicates that the package does "only the minimal amount of escaping," which suggests the regex likely targets only the essential RegExp metacharacters rather than an exhaustive set.

Since the indexed code doesn't contain the implementation details, I recommend reading the source files directly in the repository to see the exact regex pattern used.

FOLLOW_UPS:

• What are the specific regex metacharacters being escaped?
• How does this differ from RegExp.escape() behavior?
• Are there any edge cases in the escaping logic?
