​​​​Pure functions are easier to read, understand, test, debug and much more. You may have already heard all of that before. The questions are: what are these pure functions? how do they look like? or can we write the whole application using only pure functions?

​​Let’s create and compare a fairly standard To Do App written in React and Vue.

​​A large video hero can be a neat experience when done well — but adding video capability to the homepage is just asking for somebody to go in and add a 25mb video and throw all your performance optimizations out the window.

​​Template literals in JavaScript are basically regular strings on roids. The syntax for writing them is with backticks instead of regular string quotes. You can place expressions into those template literals which will be evaluated and replaced with the resulting values of those expression

​​Before event-driven programming became popular, the standard way to communicate between different parts of an application was pretty straightforward: a component that wanted to send out a message to another one explicitly invoked a method on that component. But event-driven code is written to react rather than be called.

​​Deciding on a JavaScript framework for your web application can be overwhelming. Angular and React are very popular these days, and there is an upstart which has been getting a lot of traction lately: VueJS. What’s more, these are just a few of the new kids on the block.

Webpack is the leading module bundler for React and Redux apps. I think folks using Angular 2 and other frameworks are also using it a lot these days.

​​The history of computing can be divided into an Old Testament and a New Testament: before and after electronic digital computers and the codes they spawned proliferated across the earth. The Old Testament prophets, who delivered the underlying logic, included Thomas Hobbes and Gottfried Wilhelm Leibniz. The New Testament prophets included Alan Turing, John von Neumann, Claude Shannon, and Norbert Wiener. They delivered the machines.

​​I’m a developer advocate and a backend developer, and my frontend development expertise is relatively weak. A while ago I wanted to have some fun and make a game in a browser; I chose Phaser 3 as a framework (it looks quite popular these days) and TypeScript as a language (because I prefer static typing over dynamic). It turned out that you need to do some boring stuff to make it all work, so I wrote this tutorial to help the other people like me get started faster.

There’s much new in the world of Progressive Web Apps (PWAs) and you might be wondering how compatible they are with existing architectures using libraries like React and JS module bundlers like Webpack. Does a PWA require a wholesale rewrite? What web performance metrics do you need to keep an eye on? In this series of posts I’ll share my experience turning React-based web apps into PWAs. We’ll also cover why shipping just what users need for a route & throwing out all other scripts are good ideas for fast perf.
