How does this function validate its input — does it throw on bad arguments?

Unfortunately, the repository has minimal indexed code coverage (8 of 8 eligible files), and semantic search didn't return results. To understand the input validation behavior, you'll need to examine the main implementation file directly. Based on the repo structure, check:

• index.js or index.ts — the primary export that implements escapeStringRegexp

The README doesn't mention throwing on bad arguments, and the usage example simply shows escaping a string. Given that this is a minimal utility focused on RegExp character escaping, it likely accepts any string input and doesn't throw validation errors. However, to confirm the actual behavior (whether it coerces arguments, validates types, etc.), you should read the implementation directly.
