| 3 … | +functional system programming. | ||

| 5 … | +Recently, a functional style of programming | ||
| 6 … | +has become very popular in the front end. | ||
| 7 … | +react, cycle.js, choo-choo, etc. | ||
| 4 | 8 … | ||
| 9 … | +At first, I was deeply skeptical, as a single | ||
| 10 … | +shared state object seemed to throw out the idea | ||
| 11 … | +of encapsulation. But then I started to find uses | ||
| 12 … | +for the idea of a shared state. Encapsulation is good, | ||
| 13 … | +but being explicit about state is also very good. | ||
| 5 | 14 … | ||
| 15 … | +The pattern of separating effects from state is very | ||
| 16 … | +good for systems programming - because on of the hardest | ||
| 17 … | +things is dealing with all the possible permutations of event | ||
| 18 … | +orderings. If you can replay events, and generate events | ||
| 19 … | +in different orders, it's possible to get free test coverage | ||
| 20 … | +of possible race conditions. | ||
