i finally found this snippet of code. but i didn’t how the first line works. in other words, i didn’t understand the syntax of the first line.
const gcd = (a, b) => a ? gcd(b % a, a) : b; const lcm = (a, b) => a * b / gcd(a, b); //Then use reduce on given array of integers: [1, 2, 3, 4, 5].reduce(lcm); // Returns 60
