Dummu - Naming Convention in Kotlin

A name is the first and cheapest form of documentation a reader ever gets.

Why this matters for Kotlin

This is a bold claim, an italic aside, and an underlined point, all in one Kotlin example.

What it touches:

• The Kotlin runtime or interpreter
• Whatever calls the code around it
• Anyone reading this six months from now

How to apply it:

1. Read the snippet below once, slowly.
2. Try changing one value and predict the output before running it.
3. Compare your prediction against what actually happens.

"If the name needs a comment to explain it, the name is wrong."

fun double(n: Int) = n * 2

Reference: Kotlin documentation

If the name needs a comment to explain it, the name is wrong.
