Getting Started with FEEL (Friendly Enough Expression Language) for Citizen Developers

Friendly Enough Expression Language (FEEL) is a part of the DMN specification of the Object Management Group. It is designed to write expressions for decision tables and literal expressions in a simple way that can be easily understood by business professionals and developers. Because FEEL is so flexible and readable, it is used in a number of places in Camunda 8, including DMN tables and BPMN models, and by a variety of users with different levels of technical expertise. In this video, Developer Advocate Nathan Loding provides an introduction to FEEL for citizen developers–those individuals who might be coming to Camunda and starting to use BPMN and DMN without a software engineering background or with little to no experience in software development and working with various programming languages. Nathan discusses what is FEEL and how to use FEEL Playground, and brings in data from the Marvel Developer Portal to show FEEL in action.
