Performance Under Pressure
The following is a transcript of a talk given at various events throughout 2016, including Smashing Conf NYC, and An Event Apart Chicago. I’d like to begin with an exercise in relaxation. As many of you know, I am the picture of mellowness—ol’ Namasté Marquis, they call me. So, close your laptops. Close ’em. No […]

How BoxArt Provides Fast DOM Animations

This time, we are going to look at some features of how Animated optimizes animations for performance. The Beastliness of Layout Thrash There’s a performance nightmare constantly threatening when you’re animating in the browser. As […]

Smaller, Faster Websites
The following is a transcript of a talk given at various events throughout 2015, including Bocoup’s own TXJS and Boston JS. Transcript My name is Mat Marquis, of Marquis Home Renovation. I don’t care about websites. I’m a carpenter. That, you’ll notice, is why my slide deck looks like the side of the most badass […]

The ES2015 Nightmarefile
They tried to cover this up. In designing ECMAScript 2015 (a.k.a. ES6, a.k.a. ES2015), the authors identified a number of undesirable side effects of their work. “Why worry?” they asked. “People will be so smitten with arrow functions and block-scope bindings that they won’t care about a few measly backwards-breaking changes.” Well I care, and […]

A Facade for Tooling with NPM Package Scripts
We build a lot of software at Bocoup. Like other types of builders, we tend to grow attached to the particular sets of tools and scripts we use in our work. We don’t play favorites: my colleagues support Grunt, contribute to Gulp, and maintain stand-alone tools such as JSHint. It’s easy to take familiarity with […]

text-rendering: optimizeLegibility is Decadent and Depraved
Look, I like good typography as much as the next person—maybe even a little more. When a CSS property came along with promises to doctor all my type with ligatures and carefully calculated kerning—not some half-assed tracking, but real kerning—I jumped at it. I put text-rendering: optimizeLegibility on headings, body copy, navigation links; I slapped […]

Stabilizing ECMAScript 2015 (ES6): Teaming up with TC39 and Google on Test262
August 14, 2015. Mark your calendars. That’s my next birthday. Another important date is June 18, 2015–it’s when the ECMA General Assembly will vote on and approve the 6th edition of Ecma-262 and usher in the next era of JavaScript. On that day, all those new language features we’ve been coveting/dreading will officially enter our […]

A Day at the Races: Avoiding Random Failures in Selenium UI Tests
Selenium is an indispensable tool for developing web applications. It allows developers to write test scripts that control real browsers and ensure their applications behave in the way that users expect. Tests like these make software development much more pleasant–developers can have much greater certainty that their application is functioning correctly even after large refactoring […]

The Bocoup Open Device Lab
I’ve always been a huge proponent of building sites that work everywhere — any user, any browser, any device, any context. Websites work everywhere by default, and they stay that way so long as we know how not to break them. That’s what the Open Web means to me: ensuring that entire populations just setting […]

Designing an Exponentiation Operator for JavaScript
Update: This proposal now has two open bugs for implementation, on V8 and SpiderMonkey. https://code.google.com/p/v8/issues/detail?id=3915 https://bugzilla.mozilla.org/show_bug.cgi?id=1135708 In this article, I’ll explore the process of adding syntax to a programming language by going through the process of designing a new JavaScript exponentiation operator, which I’ve submitted to TC39 for consideration in ES7. In many programming languages, […]
