Write a JavaScript program to check if a given number is even or not.Checks whether a number is odd or even using the modulo (%) operator. 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 ...

Example: Check Prime Number // program to check if a number is prime or not // take input from the user const number = parseInt(prompt("Enter a positive number: ")); let isPrime = true; // check if number is equal to 1 if (number === 1) { console.log("1 is neither prime ...
Check if number is even or odd: ((n & 1) === 0) // true if even ((1 & 1) === 0) // false ((2 & 1) === 0) // true The how: // 1 & 1 00000001 // 1 00000001 // 1 --- 00000001 // 1 (odd) // 2 & 1 00000010 // 2 00000001 // 1 --- 00000000 // 0...

We can use the modulo operator to determine whether a number is even or odd, as seen with this function: // Initialize function to test if a number is evenconstisEven=x=>{// If the remainder after dividing by two is 0, return trueif(x%2===0){returntrue;}// If the number is ...
const isDivisible = (dividend, divisor) => dividend % divisor === 0; // isDivisible(6,3) -> true Even or odd number (判断奇偶数) 使用模运算符(%)来检查数字是奇数还是偶数。如果数字是偶数,则返回 true ,如果是奇数,则返回 false 。
