Syntax Checker on item node and function node

I’m currently using item and function nodes to convert complex data structures. Every once in a while the code can contain multiple data structures, iterations, and pushing of objects (usually not more than 30 rows of code).

As I use Hooks that are hard to test, I only see syntax errors (happens :wink: ) once they are live.
Would it be an issue to have the function node and item node include an es6 syntax checker? (the basic stuff like variable declaration but not used, incorrect brackets, etc)
