What Is Angular? Google's Web Framework, From AngularJS to Signals

Tue, 20 Oct 2026 18:00:00 +0000

Most web pages are documents. Some are applications: a mail client, an analytics dashboard, a banking back office, a cloud console. Those have hundreds of screens, thousands of components and teams of dozens of people working on them for years, and building them directly on the browser’s DOM and event loop quickly becomes unmanageable. Angular is Google’s answer to that problem: a complete, opinionated framework that decides how such an application is structured, compiled, tested and shipped.

What Is React? Components, Rendering and the Library Behind Modern Interfaces

Tue, 20 Oct 2026 18:00:00 +0000

React is a JavaScript library for building user interfaces out of components: small functions that describe what a piece of the screen should look like for a given state. You never tell React how to change the page; you describe what it should be now, and React works out the smallest set of changes that gets the screen there. The idea met a cool reception when Facebook released React in 2013; today React is the most used library of its kind. In Stack Overflow’s 2026 Developer Survey, 42 percent of respondents said they had used it, second among web frameworks and technologies only to Node.js.¹

How Does a Web Browser Work? From a URL to Pixels on the Screen

A web browser is probably the most complex program most people use every day. 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 (What Is an Operating System?), running untrusted code from every site you visit and keeping those sites apart.
