Question

Tell me please, why this solution doesn't work? const isPrime = (num) => { for (let i = 2; i <= num && num%i !== 0; i++) { if (i === num) { return true; } } return false; }; export default isPrime; OUTPUT: ``` FAIL tests/solution.test.js ● prime expect(received).toBeTruthy() Expected value to be truthy, instead received false at Object..test (__tests__/solution.test.js:14:65)

R. D. · Answer

Hey!
Check out what the system says:
```
 FAIL  tests/solution.test.js
  ● prime
expect(received).toBeTruthy()

Expected value to be truthy, instead received
  false

at Object.<anonymous>.test (__tests__/solution.test.js:14:65)
```
Open tests_/solution.test.js file, line 14. There is a test that describes how Hexlet checks if your solution is correct. At that particular line there is a certain number that should be detected as prime (i.e., your function should return true), but your function returns false.
Then try to replicate how your function works while checking that particular number. Something is wrong with the logic there.

Use Hexlet to the fullest extent!
