Kotlin Arrow

A lot of Kotlin features can be traced back to functional programming languages, eg

• Heavy use of immutability-by-default and map, filter etc functions
• Type inference
• Data classes (which enable pattern matching)
• Null safety and dealing with the absence of values

However, Kotlin is missing many incredibly useful data types that are ubiquitous in functional programming languages, eg Either, Try etc.

// My basic render function structure:
function RenderLogicExample({
  someBoolean, // 1) Destructure values from `props` object
  someList,
}) {
  // 2) Declare state values
  const [a, setA] = useState(0);
  const [b, setB] = useState(0);
