Get the first element of the pair (car)
pairPair<A, B>
const pair = cons(5, 'hello');
car(pair); // 5Returns A
Get the second element of the pair (cdr)
pairPair<A, B>
const pair = cons(5, 'hello');
cdr(pair); // helloReturns B
Pair constructor (cons)
aAbB
const pair = cons(5, 'hello');
const pair = cons(cons(1, null), 'world');Returns Pair<A, B>
Check if the passed argument is a pair (isPair)
consPair<A, B>
const pair = cons(5, 'hello');
isPair(pair); // true
isPair(5); // falseReturns boolean
Convert a pair to a string (toString)
pairPair<A, B>
toString(cons('', 10)); // "('', 10)"
toString(cons('one', 'two')); // "('one', 'two')"Returns string
