Performance

Section • 4 episodes • 3 hr 4 min

Performance is particularly important for parsing because you will often need to parse megabytes, or potentially gigabytes, of data. We show that although our parser library has taken some steps towards efficiency, there is still a lot of room for improvement. We will also compare the combinator style of parsing to other more popular styles, and see that combinators can be nearly as performant as more ad-hoc styles.

Parsing is just one of many problems functional programming solves by defining a core, composable, transformable unit. We apply these exact same techniques to randomness and even app architecture!
