Test-of-localStorage-limits-quota

Test of localStorage limits/quota using bisection algorithm

I wrote this simple code that is testing localStorage size in bytes.

const check = words => {
  try {
    localStorage.clear();
    localStorage.setItem('a', '0'.repeat(words));
    localStorage.clear();
    return true;
  } catch(e) {
    localStorage.clear();
    return false;
  }
};

I have the same results on desktop chrome, opera, firefox, brave and mobile chrome which is ~5Mbytes

And half smaller result in safari ~2Mbytes
