Garbage collection in V8, an illustrated guide
This guide is unlike others I’ve done so far, and has a bit of a narrative to go along with the sketches. I thought the entire concept of garbage collection and how it gets dealt with in javascript, or more specifically in engines that run javascript, deserves a bit more of an explanation. I would also like to mention that this guide is meant to be beginner friendly, and does not cover every aspec
Preload, Prefetch And Priorities in Chrome
Today we’ll dive into insights from Chrome’s networking stack to provide clarity on how web loading primitives (like <link rel=“preload”> & <link rel=“prefetch”>) work behind the scenes so you can be more effective with them. As covered well in other articles, preload is a declarative fetch, allowing you to force the browser to make a request for a resource without blocking the document’s onload e
Comparing the Performance between Native iOS (Swift) and React-Native
This article was reformatted for the React Native Log from my published Summa Cuma Laude thesis at the University of Florida. If you wish to read the original, here is the link: https://ufdc.ufl.edu/AA00058596/00001 React-Native is a cross-platform mobile framework that lets you build apps using only JavaScript. However, unlike other hybrid mobile technologies, you are not building a “mobile Web A
Instapaper Outage Cause & Recovery
The Instapaper service experienced an extended outage between Wednesday, February 9 at 12:30PM PT through Thursday, February 10 at 7:30pm PT. We brought the Instapaper service back up with limited access to archives as a short-term solution while we worked to restore the service completely. Today, February 14, we completed the full recovery of the service. The critical system that failed was our M
JavaScript Start-up Performance – Dev Channel – Medium
Update: The Cost Of JavaScript In 2019 is now available to read. As web developers, we know how easy it is to end up with web page bloat. But loading a webpage is much more than shipping bytes down the wire. Once the browser has downloaded our page’s scripts it then has to parse, interpret & run them. In this post, we’ll dive into this phase for JavaScript, why it might be slowing down your app’s
#OSSThanks + some thoughts - Henry - Medium
I wanted to give a shout out to the folks who helped me get started in Open Source and lead me to my current involvement today. I’m hoping this can be encouraging to folks who also want to be involved. Before doing open source, I was having fun making random visualizations using Mike Bostock’s awesome d3 library and being excited about learning about bootstrap. Of course I made a twitter map. I di
🚀 webpack 2 and beyond 🚀
Today we’ve published webpack 2 to npm under the latest tag on npm! You can install it in your project using npm install webpack. 👀 Why Update? 👀The upgrade from webpack 1 to 2 comes with some very exciting features. 🙅 ES6 Support 🙅You no longer have to use babel to transpile import and export statements in your code. webpack now supports parsing of these statements. This allows us to leverag
🎉 webpack 2.2: The Final Release 🎉
Last month we shipped our first Release Candidate for webpack 2.2. Since then, we’ve been hard at work fixing any bugs that you reported. Not only that, but we’ve merged over 220 pull requests from the community in helping us refactor our core library to ES2015 (yes, this means our minimum supported NodeJS version is now 4.3). On behalf of the entire webpack team, I’m proud to announce that webpac
Introducing Inferno 1.0
The fastest UI library and the team behind itFirstly, what is Inferno?Inferno is a lightweight, blazingly-fast, and mobile-efficient JavaScript library. Derived from React, Inferno’s architecture & lifecycles will feel familiar, but its computational engines render it a totally different beast. Inferno stands as one of the fastest frameworks available and has been developed from the onset with a f
MobX 3 released: Unpeeling the onion
I’m proud to announce that MobX 3 is generally available! Version 3 doesn’t introduce many new concepts, nor did barely anything change in the core algorithm. But the API has received many improvements. The API is now more coherent, and it paves the path towards a Proxy based Mobx implementation (to be made once all major web browsers support this move). The full details of all the breaking and no
Compiling Rust to WebAssembly Guide
So you are intrigued what WebAssembly is and want to try it? Since December 22 it’s possible to compile Rust to WASM. If you don’t know anything about Rust language, I recommend you to read about it, it’s awesome! However you don’t need to know how to write programs in Rust for this guide. I’ve been stuck many times before I ran WASM in VM. I’ve spent hours figuring out what’s wrong on each step a
webpack 2.2: The Release Candidate
The talks of webpack 2 started back in January of 2015. Since then we have published multiple versions from 2.0 to 2.1-beta.28. For awhile, things were moving slowly, and then as of June, we had formed a Core Team, conducted weekly meetings, published meeting notes, and completed our first milestone for our brand new documentation webpage. In addition, we secured our organization for the future th
Immutable.js, persistent data structures and structural sharing
Treating your data as immutable brings many benefits. In fact, that’s a principle behind React: React elements are immutable. You might also be interested in learning about an Immutable App Architecture. But what’s the benefit of using Immutable.js: function toggleTodo (todos, id) { return todos.update(id, (todo) => todo.update('completed', (completed) => !completed ) ) }…over using normal JavaScr
