# Use Stream::map
# Description
Extracts a block from the body of the consumer of the Stream::forEach method and introduces Stream::map instead.
This makes complicated code blocks easier to read and reuse.
# Benefits
Arguably the lambda expression is easier to read and can be combined with other stream operations.
# Tags
# Code Changes
# Unwrapping single statement
