sync

 In a sync expression, all expressions in the sync block run concurrently and must complete before the sync expression yields control back. sync is a structured concurrency expression.

You can use the sync expression to run two or more async expressions at the same time. For example:

|  |  |
| --- | --- |
|  | # All three async functions effectively start at the same time |
|  | Results = sync: |
|  | AsyncFunction1()  # task 1 |
|  | AsyncFunction2()  # task 2 |
|  | AsyncFunction3()  # task 3 |
|  | # Called after all three tasks complete (regardless of order) |
|  | MyLog.Print("Done with list of results: {Results}") |

All three async functions effectively start at the same time

Results = sync: AsyncFunction1() # task 1 AsyncFunction2() # task 2 AsyncFunction3() # task 3

Called after all three tasks complete (regardless of order)

MyLog.Print("Done with list of results: {Results}")
