### <a name="c3.17"></a> 3.17 Ranges
This section describes guidelines for working with ranges.

#### <a name="r3.17.1"></a> 3.17.1
When creating a range with excluded upper boundary, instead of using range function with included upper boundary (`rangeTo` or `..`)
it's preferred to use a range function with excluded upper boundary (`until`).
Invalid example:
```kotlin
0..(a-1)
```
Valid example:
```kotlin
0 until a
```

Instead of `rangeTo` function it's preferred to use `..` operator.
