## `case()`

`case(condition1: bool, value1: any [, condition2: bool, value2: any, ... ] [, else: any]) -> any`

Returns the first value for which the corresponding condition is true. If no condition is true, returns null.

**Example:**

```
panther_logs.public.aws_alb
| extend avg=toscalar(panther_logs.public.aws_alb | summarize agg.avg(receivedBytes) by clientIp)
| project bytesSize=case(receivedBytes > avg, "larger", receivedBytes < avg, "smaller", "same")
```
