FEEL Cheat Sheet: DMN Expressions by Example
· 8 min read
FEEL - the Friendly Enough Expression Language - is what you write inside every DMN decision table cell and, in QuantumBPM, in every BPMN condition and I/O mapping. It is small, but it does not look like the languages most of us came from: equality is =, lists start at 1, function names have spaces in them, and there is no map.
This is the page to keep open while you write it. Every section works on the same sample order, and every section ends with a link that opens it in the FEEL playground with the data already loaded, so you can press Run and change things.
