Replay's Time Travel Debugger now supports CoffeeScript, a language known for its syntactic sugar and simplified syntax, such as omitting parentheses and utilizing comprehensions for lists. CoffeeScript code, which features clean syntax without the need for curly braces in key/value pairs, is transpiled into readable ES2015, ensuring both original and compiled code remain clear and debuggable through Replay Source Maps. Although CoffeeScript's source maps currently lack some original expressions, the language's contribution to innovation since 2009 is acknowledged. Replay's investment in general Source Map support means that various language features, including those of CoffeeScript, JSX, and TypeScript, are effectively integrated, allowing for seamless debugging experiences.
