How to check if product of every adjacent pairs exists in an array with Node.js

Answer 1

function check_product_of_every_pair(array) {
    for (let i = 0; i < array.length; i += 2) {
        let product = array[i] * array[i + 1];
        console.log(array[i] + " * " + array[i + 1] + " = " + product);
        if (array.find(e => e === product) == undefined) {
            return false;
        }
    }
    return true;
}
        
const array = [2, 3, 6, 7, 42, 0];

console.log((check_product_of_every_pair(array) ? "Yes" : "No"));



 
/*
run:
  
2 * 3 = 6
6 * 7 = 42
42 * 0 = 0
