The idea is:
When using code node, the development step requires multiple comes-and-goes to check for syntax and data quality. Inbetween, it would be nice to have checkpoints and variable content checking.
My use case:
Usual slice-and-dice use case for an array of objects.
I think it would be beneficial to add this because:
It will improve the low-code user experience.
Are you willing to work on this?
Not really, but I wish, someone with more experience would.
