The code part of low code is the easy part. It's integration with other things: API's, database engines, etc. The point of low-code is to give people without a coding ability the ability to connect systems together and perform transforms on the way, wrapping a SQL database with unique business logic and routines, or respond to real world events in an easy fashion (user purchases product, object state transitions from X to Y, a file appears in an FTP directory or a cloud storage bucket, an email is received, etc)
