 ### Concurrent function
 
-The `Concurrent` function allows multiple formulas specified within the same property to be evaluated at the same time if they have connector or Dataverse calls. Normally, multiple formulas are evaluated by chaining them together with the `;` (semi-colon) operator, which evaluates each formula sequentially. With the `Concurrent` function, the app will evaluate all formulas within a property concurrently even after using the `;` operator. This concurrency helps users wait less for the same result. When data calls don't start until the previous calls finish, the app must wait for the sum of all request times. If data calls start at the same time, the app needs to wait only for the longest request time. [Learn more](/power-platform/power-fx/reference/function-concurrent) about the `Concurrent` function
