Potentially stupid question: is there a tool that can show you where in the code a parser error happened? I run into this a lot when refactoring code, where I end up with a parser error which prevents Prettier/TS etc from running. It takes a lot of effort to locate the problem.https://twitter.com/acemarke/status/1174356298227490816 …

Yep. There's dedicated error messages for every single possible syntax error, no more "Unexpected token". Some errors also use other contextual and token information to provide suggestions if it thought you meant something else.
Specific issue here seems to be excessive curlies? When Rome expects a closing character, like } or ], then it will also point to the location of the opening character that made it expect it.
