// Start meditation
// 5
// 4
// 3
// 2
// 1
// Jay Guru Dev

Coding Exercise 02

Change isPrime function below to run asynchronously using Promise.

• if the input is prime number, the promise resolves with { prime: true }.
• if the input is not a prime number, it rejects with { prime: false }.

const isPrime = (n: number) => {
    for (let i = 2, s = Math.sqrt(n); i <= s; i++)
        if (n % i === 0) return false;
    return n > 1;
};

When you finish, test using the code below:

console.log('start');
isPrime(7)
    .then(console.log)
    .catch(console.error);
console.log('end');

// start
// end
// { prime: true }

Make changes to provided test and use async/await instead of .then() and .catch()
