Description
If the body of the lambda statement contains only a single expression, the braces are optional. It can be reduced to a lambda expression.
This is comparable to if-statements or loops with a single expression inside their body, where braces are also optional.
Benefits
This rule provides an easier-to read alternative to filter items in a list.
