+/**
+ * Creates a function that checks conditions one by one and runs the matching function.
+ *
+ * Each pair consists of a condition (predicate) and a function to run.
+ * The function goes through each condition in order until it finds one that's true.
+ * When it finds a true condition, it runs the corresponding function and returns its result.
+ * If none of the conditions are true, it returns undefined.
+ *
+ * @param pairs - Array of pairs. Each pair consists of a predicate function and a function to run.
+ * @returns A new composite function that checks conditions and runs the matching function.
+ * @example
+ *
+ * const func = cond([
+ *   [matches({ a: 1 }), constant('matches A')],
+ *   [conforms({ b: isNumber }), constant('matches B')],
+ *   [stubTrue, constant('no match')]
+ * ]);
+ *
+ * func({ a: 1, b: 2 });
+ * // => 'matches A'
+ *
+ * func({ a: 0, b: 1 });
+ * // => 'matches B'
+ *
+ * func({ a: '1', b: '2' });
+ * // => 'no match'
