In a few hundred milliseconds it turns a line of text in an address bar into a network connection, a stream of bytes, a tree of objects, a set of styled and measured boxes, and finally pixels, then keeps all of that live while scripts change it and the user scrolls, types and clicks. It is also a small operating system in its own right (<a href="https://lab.artur-rios.tech/fundamentals/operating-systems/">What Is an Operating System?</a>), running untrusted code from every site you visit and keeping those sites apart.</p>
