What color is your function?
The article uses the metaphor of 'red' (async) and 'blue' (sync) functions to explain how asynchronous programming divides codebases and complicates composition. It argues that while async/await improves syntax, only languages with threads or coroutines, like Go, eliminate the distinction, allowing code to remain 'colorless' and composable.
