Write a JavaScript program to check whether a given positive number is a multiple of 3 or 7.This JavaScript program checks if a given positive number is a multiple of either 3 or 7. It uses the modulo operator (%) to determine if the number is divisible by 3 or 7 without any remainde...

Returns true if the number is even, false if the number is odd. Sample Solution: JavaScript Code: // Define a function 'isEven' that checks if a number 'num' is evenconstisEven=num=>num%2===0;// Test cases to check if numbers are evenconsole.log(isEven(3));// false (3 is not...

A prime number is a positive integer that is only divisible by 1 and itself. For example, 2, 3, 5, 7, 11 are the first few prime numbers. Example: Check Prime Number // program to check if a number is prime or not // take input from the user const number = parseInt(prompt("...
for (var x = array_n_element; x > array_n_element - 3; x--) { product1 = product1 * sorted_array[x]; } product2 = sorted_array[0] * sorted_array[1] * sorted_array[array_n_element]; if (product1 > product2) return product1; ...
