Question Инна Панченко in lesson «Pure functions and side effects», course «Intro to Programming»

Инна Панченко

Help me, please. I don;t understand my mistake. The Output said so amasing thing: ` FAIL tests/solution.test.js ● solution

expect(received).toBe(expected)

Expected value to be (using ===):
  "Hello, World!"
Received:
  ", !"

  at Object.<anonymous>.test (__tests__/solution.test.js:4:79)

✕ solution (6ms)

Test Suites: 1 failed, 1 total Tests: 1 failed, 1 total`

My code is:

```import * as strings from './strings';

// BEGIN (write your solution here) const solution = (str) => { let result = ''; for (let i = 0; i < strings.length(str); i += 1) { if (strings.toUpperCase(str[i]) === str[i]) { result = result + str[i]; } }

return String(result); }; export default solution; // END

What's wrong with letters?
As for me, the cause lies in the

if (strings.toUpperCase(str[i]) === str[i]) { result = result + str[i]; }
