Lisp inspired conditional construct (COND) in Javascript.
COND is a function which takes an arbitrary number clauses. Each clause contains a list of two expressions. First expression is a condition (or predicate) and the second is the result. Each clause is ran in order, immediately returning the result where the condition is truthy.

const fn = cond([
[t => t === 0, `Water freezes at 0°C`],
[t => t === 100, `Water boils at 100°C`],
[true, t => `Nothing special happens at ${t}°C`]
]);
console.log(fn(0)); // 'Water freezes at 0°C'
console.log(fn(50)); // 'Nothing special happens at 50°C'
console.log(fn(100)); // 'Water boils at 100°C'npm testMIT
