Function branch

Applies the transform corresponding to the first matching condition, or the fallback transform if no predicate from conditions matches.

Example

import * as L from "flurp/logic";

const f = L.branch([
  [N.isGt(100), N.multiply(0.9)],
  [N.isGt(50), N.subtract(5)],
  [N.isGt(0), L.identity],
], L.always(0));

f(500);     // 450
f(100);     // 95
f(30);      // 30
f(-10)      // 0
