Setup and first program

The essential idea

Setup and first program makes a Kotlin program more expressive while keeping the code readable. Identify the value, the rule, and the result before you try to remember the syntax.

Run a tiny experiment

Read top to bottom, then run the code and use its output as evidence.

fun main() {
    println("Namaste, Kotlin!")
}

Output:

Namaste, Kotlin!

A practical habit

For Setup and first program, run a very small example and change only one part. The compiler and output will show whether your explanation is correct.
