# Kotlin Pro

## Overview

Kotlin's pitch — **a pragmatic, null-safe, concise language for the JVM and Android** — is
delivered through its type system and coroutines. Professional Kotlin means using null safety as
designed (not fighting it with `!!`), modeling with data classes and sealed hierarchies, writing
suspend functions instead of callback chains, and keeping the functional sugar readable rather
than clever.

The through-line: concise but explicit — Kotlin brevity should clarify, never obscure.
