Debugging Javascript - General Guidance
I’m looking for General Guidance, not a solution to a specific problem!
I have a lot of experience programming in server-side languages like C++, C#, T-SQL, PL/SQL, and others… but am very much a n...

Thanks for the rapid reply!
I’m hoping that a long-term Snaplogic user might chirp up with some phenomenally useful tricks that let me find problem code in our JS snaps and fix it.
For most transformations, the SnapLogic expression language can be used. We support dynamic validations, which enables rapid prototyping and development.
For more complex requirements, a custom Snap can be developed in Java. Full IDE support is possible through debugger support. A custom snap has performance advantages over a Script snap when the document count is large, but the development of the custom snap does require more effort.
For the Script snap, using log statement to debug the script is one approach. Another approach is to develop the script outside of SnapLogic, using the command-line version of the language to test the script and then upload the script into SnapLogic. This works well for Jython, I believe the same approach works for JavaScript.
