JavaScript: String characters
Access individual characters using bracket notation with a zero-based index.
const word = 'hello';
console.log(word[0]); // => h
console.log(word[4]); // => oInstructions
A secret word is hidden in the text string. Extract the needed characters from the text variable by their indexes, join them, and print the word grip.
Tips
If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:
- Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.

Your exercise will be checked with these tests:
// @ts-check
import { expect, test, vi } from 'vitest';
test('symbols', async () => {
const consoleLogSpy = vi.spyOn(console, 'log');
await import('./index.js');
const firstArg = consoleLogSpy.mock.calls.join('\n');
expect(firstArg).toBe('grip');
