Kotlin Standard Library
The Kotlin Standard Library provides living essentials for everyday work with Kotlin. These include:
- Higher-order functions implementing idiomatic patterns ([let][kotlin.let], [apply][kotlin.apply], [use][kotlin.io.use], [synchronized][kotlin.synchronized], etc).
- Extension functions providing querying operations for collections (eager) and sequences (lazy).
- Various utilities for working with strings and char sequences.
- Extensions for JDK classes making it convenient to work with files, IO, and threading.
