How does ramda.or work?

In Ramda, or is a curried function that takes two arguments and returns the result of the logical OR operation between them. It returns the first argument if it is truthy, otherwise it returns the second argument. It is also a short-circuiting function, which means that if the first argument is truthy, it will not evaluate the second argument.

const { or } = require("ramda");

const isPositive = (n) => n > 0;
const isEven = (n) => n % 2 === 0;

const isPositiveOrEven = or(isPositive, isEven);

console.log(isPositiveOrEven(2)); // true
console.log(isPositiveOrEven(-3)); // false
console.log(isPositiveOrEven(1)); // true

In this example, we define two functions isPositive and isEven that return true if a given number is positive and even, respectively. We then use or to create a new function isPositiveOrEven that returns true if a given number is either positive or even. Finally, we test the function with some example inputs using console.log.
