OK? is a modern, dynamically typed programming language created with a strong opinion: to remove needless complexity and help programmers write code that matters. It eliminates many common language features (e.g., ternary operators) in favour of a consistent, minimal syntax: for example it uses only switch statements for control flow and has only one comparison operator. OK? also treats errors as plain values (strings/arrays) and removes inheritance in favour of what it calls “evolution over composition.” The language emphasises readability and pushing logic out into functions so cases remain simple. It includes concurrency via a map function that executes callbacks in parallel. The project is illustrative of Duffield’s vision: code should feel “magical to write” by removing what is unnecessary.
Features
- Single control-flow construct: switch statements (no if or ternary)
- Only one comparison operator (>=) to reduce cognitive load
- Errors are just values (strings/arrays), no special exception mechanism
- Concurrency built-in via a map function that executes callbacks in parallel
- No classes, all fields private, no constructors: favouring evolution over composition
- Dynamically typed and minimal syntax aimed at clarity and readability
