Compiling (or “transpiling” or whatever) to JS

How do programming languages that compile to JS work? How are they made?

Let’s find out, together! We will go on a journey where the end result is a brand new compile-to-JS language.

ESnext Performance - Why bother?

ES2015 added a lot of sex appeal to JavaScript, and ES2016/17 make it even more sexy. Babel and friends allow everyone to use ESnext today, but lead to large JavaScript bundles and sluggish page load.

To really shine, ESnext features need to be supported natively, and they must be reasonably fast.

Look mum, no hands!

A typical interaction with a device or interface involves touching it. Either you’re pressing buttons on a controller, swiping on a touchscreen or clicking on your laptop’s trackpad. But what if you could control things without the use of your hands? What if you could use… your thoughts?

Profile image for Charlie Gerard

Charlie Gerard

I come from a marketing background and changed career a couple of years ago to become a developer. I started my dev career as a Software Developer and consultant @ ThoughtWorks in Sydney, working on various types of projects from small websites for startups to complex software for big corporations. I quickly developed a great interest in tinkering with hardware, cutting edge technologies and creative coding. Therefore, I have spent a lot of my personal time over the past few years prototyping projects to mix technology, design and art.

I also contribute to the community by writing tutorials about my experiments and by giving talks at meetups and coding bootcamps to share my passion for creative technologies and hopefully motivate developers to explore that space. I recently moved to London in the hope of being part of more innovative projects.

JavaScript engines - how do they even?

Want to know how JavaScript engines work? Why is JavaScript so fast? What is just-in-time compilation? We’ll look at basic concepts of compilers, challenges posed by modern JavaScript, and how to write compiler-friendly JavaScript.

Jan Krutisch

Currently in transition to becoming a proper grey beard, I’m old enough to remember a world without the web, or cyberspace as we used to call it.

I’m a web developer by day, working on tools for designers and developers at Flowbyte, and a musician and general digital artist by night. Actually, usually I sleep at night, but you know what I mean.

JavaScript therapy

Generator functions are pause-able(!) functions, a strange concept that only gets stranger as you learn to put generator code inside while (true) loops(!!).

This talk aims to help, just like the classic therapist program Eliza, which we’ll reimplement on our path to understanding generators.

Jana Beck

Jana Beck is a coffee-fueled engineer at a small open-source and not-for-profit startup called Tidepool, based in the Bay Area of California but with developers on three continents. Tidepool’s mission is to reduce the burden of type 1 diabetes through data technology, and Jana works mostly on Tidepool’s front-end stack (React with redux; D3 for data visualization).

When she’s not coding or sleeping, there’s a high probability that Jana is sweating in a gym or a dance studio.

Type systems will make you a better JavaScript developer

Flow and TypeScript promise “types in js” - but what does that get you, exactly? What’s the experience of adding types to a large project? Is the overhead worth it for you and your team? In the end, type systems will give you more confidence in your code, fewer bugs, and a much friendlier codebase.

Who Gives a Fuck About a Monad? Functional Programming for People Who Hate Math

Functional programming means cleaner code, easier maintenance, and simpler testing, but most of us will never use it because it’s explained in such a complex, mathematical, and confusing way. This talk explains how we can get the benefits of functional programming today — no math required.

Time and Time Again: Fixing Dates in JS

In JavaScript, times and dates can take many forms, but none of them represent a complete, unambiguous answer to the simple question “what time is it?”. While almost anyone can look at a clock at determine what time it is, it turns out that humans encode an enormous amount of hidden information into their representations of date and times. Because computers don’t have the benefit of knowing about this hidden information, times can be much more ambiguous.

In this talk, we’ll show how to extend our mental model of JS dates and times so that they become useful. Starting from our everyday understanding, we’ll progress through successively larger and more comprehensive representations until we get to a much more complete picture of how things should work. By the end of the talk, you’ll have an appreciation for how complicated dates and times really are, and you’ll be able to confidently avoid the most common pitfalls.

A Room With a Vue

In this crazy jungle of js frameworks, we got yet another one. Vue.js was officially released in late 2015 and started accumulating followers during 2016. Today it is already released as a 2.0 and a serious contender to React and Angular. I will tell more about this outsider.

JavaScript and Civil Rights: Using Your Skills For The Good of the People

Accessibility is a civil right. We can take inspiration from Norway’s strict accessibility policy and make a business case for inclusion by building it into our projects using open source JS tools. I want to teach developers everywhere they are capable of making a big difference with code.

Building a Scalable Pub/Sub system with UpRing

The world is real-time: our users expect to receive live notifications, updates, and use extremely reactive interfaces. In a real-time world, we might want to connect physical things, each of them with their own live connection to the cloud. Delivering live notifications has always been a complex task, but tools like WebSockets and Socket.io have enabled a wide range of applications to flourish.

Scaling those systems often turns out to be problematic. Generally an external publish/subscribe broker is leveraged to deliver the messages, with our application or the framework acting as a proxy. These brokers are usually central points of failure, and extremely difficult to scale.

UpRing is a distributed system framework for building applications on top of a Consistent Hashring. In other words, UpRing is a P2P system for cloud applications. With UpRing, all the notifications for a single element are routed through the same server, removing the central point of failure and allowing for fine-grained elastic scalability in ratio to the amount of current users.

Doing the Unstuck: How to make browsers compatible with the web

What does it mean for JavaScript and CSS to be — or not to be — compatible with the web? Is it possible for a site written today to continue to work in 10 years? Likewise, could existing code complicate adding language features or fixing mistakes in web APIs?

In this talk I'll discuss the issues that arise when browsers attempt to clean up the web platform, either by adding new language features and DOM APIs or removing old ones — while attempting to remain backwards compatible. I'll even talk about some controversial moves made by browsers to support non-standard (cough webkit prefixes) CSS and JS.

Bringing Back the 1990s: The Revenge of JavaScript Style Sheets

JavaScript Style Sheets were an early competitor to CSS. Spoiler alert: CSS won. In the decades since, JSSS has had a growing influence on how we thinking about styling web applications. CSS and SASS cribbed a few moves from JSSS and some emerging approaches are set to bring it back from the dead.

Security Starts With You: Social Engineering

Virus? There’s an app for that. Malware? There’s an app for that. Social engineering? It’s a little more complicated.

Aimed at average users who could be targeted by such an attack, I will look at the tools of social engineering, how to avoid them & why companies fail to prep employees for attacks.

Workshops

Get hands on with other Web Rebels

Workshop: Learn to P2P

Come join the latest chapter in our series of "Learn to P2P" workshops.

The focus will be how to build systems that support streaming and sharing of real time data. The workshop will consist of a series of small iterative exercises that will take you through the basics of networking and distributed systems, all the way to learning how you can make your own P2P TV and radio stations.

There will be content for everybody, no matter your skill level. We'll be using Node.js but the techniques will work across any programming language.
