Summary

This lesson unpacks the basic syntax structure of Kotlin. In Kotlin, the play function can be written without parameters and does not require class wrapping at the outermost level. This makes the syntax of the beginner program very clean, straight to the core of the problem, and easy to read.

Key points

The keyword 'fun' is used to declare a function
The main() function is the starting point of the application and does not require a declaration of the packing class
The instruction block is written in curly braces '{' and '}'
The writing of the semicolon (;) is optional at the end of the instruction line
