Upgrading JavaScript's collections
Phil Nash, Developer relations engineer DataStax
The last year has seen a flurry of activity in JavaScript's standard library. New methods have been added to the Array and Set prototypes, and Objects and Maps are getting in on the party with new static functions. We'll take a look at what all these new methods do, how they fill the gaps in JavaScript that you have likely written functions for yourself, and how they prepare the language for future upgrades. With a better standard library, you can retire some dependencies and get excited about ES2024 and beyond.
The new wave of JavaScript: A Taxonomy of Runtimes and their Web-interoperability
Ben Taylor, Staff Software Engineer Stile Education
In the last few years there's been an explosion in the ways you can run JavaScript. Node has its new dinosaur cousin Deno. They're both based on V8 from Chrome. Everybody is talking about Bun, which is faster apparently. It doesn't use V8, so what's the deal with that? There's JavaScript on Cloudflare, and a bunch of other Serverless providers. How will this impact bundling, and other front-end tooling? Does the same JavaScript work on all of them? What's the difference? What's going on?
In this talk we'll look over the history of JavaScript engines in browsers, and what makes them different. Then we'll look at JavaScript outside of browsers, featuring Node. Finally we'll explore the new wave of JavaScript engines and look at how they're trying to become Web-interoperable. I'll explore this all through the lens of how it impacts front-end developers primarily. If I get distracted I might accidentally start talking about WebAssembly. It'll be a ride!
Making Single Page Apps accessible - it's easier than you think
Jess Budd, Senior Software Engineer Hireup
Javascript frameworks get a bad rap when it comes to accessibility. But it’s easier than you think to make your JS applications accessible!
Accessible websites benefit not only people with disabilities, but improve the user experience for everyone. Follow me on a journey exploring techniques and approaches you can use to improve your projects today. We’ll look at specific code examples to address things like div soup, focus management and visibility, routing and meta data control.
We won’t just describe the issues, we'll cover how to address them as well. You’ll walk away knowing how to ensure your website or application is accessible and inclusive for everyone.
