Write a JavaScript function that checks whether a given number is prime or not.
function isPrime(number) { if (number <= 1) { return false; } for (let i = 2; i <= Math.sqrt(number); i++) { if (number % i === 0) { return false; } } return true; } // Test the function const num = 29; const isNumPrime = isPrime(num); console.log(isNumPrime);
