From Assembler, over Fortran and C to modern Kotlin, we came a long way and improved the way we can express our thoughts in code.
One thing that happened during this journey is that languages allow us to use types for our problem domain, independent of the underlying computer architecture. Types became a powerful tool.
Types improve readability which probably is the most important aspect of programming! But types also prevent you from making mistakes at compile time. This is why Kotlin translated the null problem into the type system.
We can use these powers in our daily lives. We can write better code by avoiding “primitive obsession”. I’ll show you how!
