JavaScript: Check whether the first numeric argument is divisible by the second one

JavaScript fundamental (ES6 Syntax): Exercise-201 with Solution

Check Divisibility

Write a JavaScript program to check if the first numerical argument is divisible by the second one.

• Use the modulo operator (%) to check if the remainder is equal to 0.

Sample Solution:

JavaScript Code:

// Define a function 'isDivisible' that checks if 'dividend' is divisible by 'divisor'
const isDivisible = (dividend, divisor) => dividend % divisor === 0;

// Test cases to check if 'dividend' is divisible by 'divisor'
console.log(isDivisible(6, 3));     // true (6 is divisible by 3)
console.log(isDivisible(5, 3));     // false (5 is not divisible by 3)
console.log(isDivisible(100, 10));  // true (100 is divisible by 10)
console.log(isDivisible(0, 3));     // true (0 is divisible by any non-zero number)

Output:

true
false
true
true
