What does MEL stand for in MuleSoft?

Explanation:
MEL stands for Mule Expression Language. It’s the expression language used inside MuleSoft flows to read and manipulate data at runtime. You write MEL expressions inside #[ ... ] blocks to access things like the payload, flow variables, and message properties, enabling dynamic routing, filtering, and small calculations without separate scripts. For example, you might use #[payload.name] to read a field from the incoming message, #[vars.userId] to use a value stored in a flow variable, or #[now()] to get the current time. Data transformation is handled by DataWeave, while MEL handles lightweight runtime expressions within the flow.
