In many ways TypeScript is more like a powerful linting and documentation tool to author better JavaScript, rather than a separate programming language. One significant benefit of TypeScript is its deliberate support for some of the latest ECMAScript language features.

Intern has always taken a different path in the pursuit of flexible automated web app testing. In the early days, Intern leveraged AMD modules when most other testing frameworks were not modular or only supported CommonJS modules, allowing Intern to support modular code in any environment.

The ubiquity of JavaScript is undeniable; it’s the universal language of the web — a position that no other languages hold. JavaScript is flexible, able to adapt and grow as the web grows.

HalfStack is a series of tech conferences focused on half of the web development stack – specifically, the part you interface with. It lives up to its claims of being “an authentic, high value experience for attendees and sponsors focused on UI-centric JavaScript and web development.

In 2007, we were invited to speak at the Apple WWDC event. At the time we didn’t know why we were invited. We later learned that because there was initially no native SDK, developers were advised to use JavaScript, HTML, and CSS to create iPhone apps, and were encouraged to attend our session.

With the boom of location-based technologies like mobile location services and the Geolocation API in the browser, we have seen the growth of mapping and location inside of applications. Alongside this we have seen numerous mapping libraries appear for the web, allowing developers to build map based experiences into their apps.

As a first-time JSConf attendee, I happily embraced the welcoming culture and fun atmosphere – surfing, anyone? But I was even more impacted by the presentations centered around JavaScript expanding beyond the browser, using JavaScript to help others, and the focus on community.

Rendering large data sets in the browser while optimizing for performance and accessibility is a complex problem. The current approach to handling long lists of data is using an infinite scroll pattern to incrementally load and render data just before the data enters the view.

If you need to build a desktop application today, Electron is an increasingly common choice. It is cross-platform and is built using the same web technologies that you probably already know. We’re long-time users of Electron at SitePen, and have previously talked about Setting up Electron with Dojo.

The web is for everyone. That includes web apps built on web architecture. If you haven’t heard the word “accessibility” mentioned in the last couple of years, you may have been living under a rock. Building accessible, inclusive web apps that support users with disabilities is becoming standard protocol.

When building web apps, writing processing intensive code can be a challenge. One issue is getting predictable running times across browsers and JavaScript engines that optimise different code paths differently, as well as producing code that doesn’t interfere with user experience.

So you’ve built an amazing app using Dojo and now you are ready to go live. After a bit of research, you learn that traditional deployments are challenging! Luckily, the days of FTPing files are long gone, and we can rely on Docker for fast, reliable deployments.

Outsourcing is such a dirty word. Unbearable customer service, subpar manufacturing, and corporate downsizing all come to mind when you hear it. But outsourcing has gotten a bad rap.

Augmented Reality (AR) brings digital information or media and interweaves it with our experience of the real-world. In recent years Augmented Reality has become apparent in the consumer space in two major formats: head mounted displays such as the Microsoft HoloLens and the Magic Leap along with more widely available experiences on mobile devices.

In a previous post we looked at how to compile the popular programming language Go to WebAssembly. WebAssembly is a new programming language which provides a compact binary format for the web. In this post we’ll explore another WebAssembly target language called AssemblyScript.

Let’s be honest, getting designs from your UX team into the hands of your engineering team in a way that makes sense is rarely easy. Add tight deadlines, team changes, and miscommunication to this process and your application will likely end up looking very different than what you expected.

Esri provides the excellent ArcGIS for JavaScript API for building geospatial applications. Their approach has grown substantially over the years, from basic two-dimensional maps comparable to early Google Maps implementations to now cover nearly everything I can imagine wanting to do in a 2-D or 3-D map.

Everyone loves finding a great deal. Who can say no to a good two-for-one special? Every store has a bargain rack that’s full of unsold clothes and slashed prices.

Introduction Material design is everywhere today; even now if you’re reading this post in a Chrome browser, you may have noticed that the icons, fonts, colors and paddings have all recently been changed to align with Material.

One common complaint around web applications is that they can feel slow or clunky compared with native applications. Sometimes we find sites that can take a long time to load (let’s say longer than 3 seconds) and sometimes those sites feel non-interactive or ‘janky’ when we try to interact with them.
