Creates a function that iterates over `pairs` and invokes the corresponding function of the first predicate to return truthy. The predicate-function pairs are invoked with the `this` binding and arguments of the created function.
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'| Name | Type | Attribute | Description |
