Frequently Asked Questions
Does it escape special characters for RegExp constructor?▾
Yes, when generating code that uses new RegExp(), backslashes and other special characters are properly double-escaped.
Can I get TypeScript code instead?▾
The JavaScript output works in TypeScript as-is. The generated code uses standard RegExp APIs that are fully typed in TypeScript.
