Test262 Helps Advance JavaScript Proposals to Standardization

Test262 is a conformance test suite for ECMAScript, the programming language on which JavaScript is based. Containing 36,103 individual tests at the time of this writing, Test262 ensures that different implementations of the language, such as the JavaScript engines in web browsers or stand-alone runtimes like Node.js or Moddable XS, agree on the minutiae of […]

Porting Scratch from Flash to JavaScript: Performance, Interoperability and Extensions

Last year we formed a team focused on using the growing number of new web APIs to build multimedia applications that push the edge of the web platform. Our main work in this area over the last 2 years has been with the wonderful team behind Scratch at MIT’s Lifelong Kindergarten Group (LLK), and with […]

Charting Web Platform Interoperability in 2018

Bocoup has been a long-time contributor to the Web Platform Tests (WPT) project, helping spec writers draft testable specs and helping browser implementers test features for correctness and interoperability based on those specs. In 2018, we’ve made great strides improving the coverage of WPT, the ergonomics of writing and running tests, and the infrastructure necessary […]

Announcing Test262 Report

Today we’re launching Test262 Report to provide JavaScript developers with up-to-date information on the state of new and existing language features across implementations. Test262 Report is based on daily runs of Test262, the ECMA-262 (“ECMAScript” or “JavaScript”) test suite, in nightly builds of JavaScript engines, and visualizes at-a-glance status of feature implementation progress. Taking a […]

New Test262 Import and Runner in WebKit

Bocoup recently facilitated an update to the WebKit project’s interaction with Test262. In this article, I’ll cover what this means for the WebKit project and the JavaScript ecosystem, as well as what exactly has been done in the WebKit project to help make this process more repeatable. Test262 is a project maintained by Ecma’s TC39. […]

The State of Fieldset Interoperability

We recently started working with browser implementers to improve the state of fieldset, the 21 year old feature in HTML, that provides form accessibility benefits to assistive technologies like screen readers. It suffers from a number of interoperability bugs that make it difficult for web developers to use. Here is an example form grouped with […]

Three Cheers for Bmac

Friday, July 27 marked Brendan McLoughlin’s final day at Bocoup. Brendan (better known around the web as “bmac”) joined us way back in 2013, so there’s a lot to say about his contribution to our company. The most important thing to know about Brendan’s style (and probably the first thing you’d notice when working with […]

Adapter Pattern – A Must for Vendor & Service Integrations

Software development is a costly process. Requirements need to be gathered, decisions need to be made, and resources need to be scheduled to write the software. All of these steps require an investment of time and money to get a feature to the point where it starts bringing value to a business. After the feature […]

So, You’d Like to Start an Open Source Project

Regular readers of this blog are no strangers to free and open source software. From Firefox to Brave, Node.js to OpenSSL, and jQuery to React (finally), today’s web developer can’t get very far at all without relying on “FOSS.” However, there is a huge difference between consuming FOSS and maintaining FOSS. The latter task is […]
