If no element matches the condition, the function returns -1. Go to json2csharp.com. Was attempting something like this: For each element of the input array, in order to, reduce applies the reduction lambda expression (function), then replace the accumulator with the new result. The reduce function is about as close as we get to a general-purpose looping tool in DataWeave. [NEW] DZone's 2023 "DevOps: CI/CD, Application Delivery, and Release Orchestration" Trend Report, https://docs.mulesoft.com/mule-runtime/4.3/dw-core-functions-pluck, https://docs.mulesoft.com/mule-runtime/4.3/dw-core-functions-reduce, Dev vs. Ops: Conflicted?
