How to redirect to another page

Short answer

Assigning an address to location.href opens it, like clicking a link:

window.location.href = '/thank-you';

Without a history entry

location.replace() replaces the current page in history, so the Back button does not return to it. That is useful after a login or a form submission:

window.location.replace('/dashboard');

A new tab and reloading

window.open() opens a new tab, location.reload() reloads the current page:

window.open('https://example.com', '_blank', 'noopener');
location.reload();

Common mistake

If the address comes from a parameter, check it before redirecting. Otherwise anyone can make a link to your site that sends users to a fake page:

const next = new URLSearchParams(location.search).get('next') ?? '/';
 
if (next.startsWith('/') && !next.startsWith('//')) {
  location.href = next;
}
