JavaScript: String slices

Use slice() to extract part of a string.

const text = 'Hello, World!';
console.log(text.slice(7));     // => World!
console.log(text.slice(7, 12)); // => World
console.log(text.slice(-6));    // => orld!  (negative index from end)

Instructions

Given url = 'https://hexlet.io', extract and print the domain without the protocol:

hexlet.io

Tips

String.prototype.slice()

The exercise doesn't pass checking. What to do? 😶

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.

In my environment the code works, but not here 🤨

My code is different from the teacher's one 🤔

I've read the lessons but nothing is clear 🙄

Прочитал урок — ничего не понятно 🙄

Your exercise will be checked with these tests:

// @ts-check

import { expect, test, vi } from 'vitest';

test('slices', async () => {
  const consoleLogSpy = vi.spyOn(console, 'log');
  await import('./index.js');

  const firstArg = consoleLogSpy.mock.calls.join('\n');

  expect(firstArg).toBe('hexlet.io');
});
