At Asynchrony

900 Spruce St #700
Saint Louis, Missouri, USA

Meetup starts at 6:30pm, with 30 minutes of social time. Beginning at 7pm, Darren Cruse will present “Beyond the Callback: Yield Control with Javascript Generators”.

“A big part of JavaScript programming is its single-threaded control flow that never blocks. The result is that programs are written in ‘continuation passing style’ where functions don’t return values, they ‘call back’ instead.

“Functions can return promises, but promises themselves resolve through callbacks... so the non-blocking control flow remains. Generators are about to change that!

“Generators were designed for iterating over infinite sequences of items, but they can also be used for writing code that 'appears to block’ (while remaining single-threaded). This restores the usefulness of simple functions, which take arguments and return values.

“This talk will explore these ideas in depth, explain what generators are and how they work, and survey some ‘polyfill’ libraries that use them to provide ‘pseudo blocking’ control flow. I will also look at the ES7 async/await proposal (similar functionality – different syntax), and consider how generators can be used today. Lastly, I'll look at what (if any) performance costs come from using generators.

“By the end, I hope you will come away with an understanding of what generators are and how they can be useful to you as a JavaScript developer, and that you will have the confidence to pick up and use a generators library.”

Starting about 8:30pm, we'll move into a hacking session to experiment with the material that's been presented, and with JavaScript and Node.js in general.

Sovereign Technologies will be providing complementary pizza and beverages, so come hungry, come thirsty, bring your laptop and be ready to code!

Meetup starts at 6:30pm, with 30 minutes of social time. Beginning at 7pm, Jeff Barczewski will present ReactJS and family for the win!

“ReactJS is changing the way we build web and native apps. Come learn what makes ReactJS different from other MV* frameworks and why you should learn about it. ReactJS can be used alongside other frameworks; when partnered with react-router and flux it becomes a platform on which to build your software.

“I'll share my experience at ReactJS Conf and will illuminate where ReactJS is heading in the future. I'll explore React Native, which allows you to build native iOS and Android apps with instant round-tripping for rapid development. React Native answers the dream of reusing your JS code on all devices without sacrificing native UI and performance.

“Join me for an exciting night of challenging existing beliefs and embracing some new ideas for building JS apps.”

Starting about 8:30pm, we'll move into a hacking session to experiment with the material that's been presented, and with JavaScript and Node.js in general.

Meetup starts at 6:30pm, with 30 minutes of social time. Beginning at 7pm, Mark Volkmann will present "Using ES6 Today".

ECMAScript 6 (ES6) brings many cool features to JavaScript. However, if you wait until all major browsers support every feature before you begin using them, you'll be waiting a long time! There is a solution though – Google Traceur. This tool generates ES5 code from ES6 code.

In this talk Mark will describe how you can use this tool to enable use of ES6 features today. He will cover Traceur, JSHint support for validating ES6 code, and sourcemaps for debugging ES6 code in a modern browser.

Starting about 8:30pm, we'll move into a hacking session to experiment with the material that's been presented, and with JavaScript and Node.js in general.

Adaptive Solutions Group will be sponsoring complementary sodas and sandwiches, and you're welcome to BYOB, so come hungry, come thirsty, bring your laptop and be ready to code!

Meetup starts at 6:30pm, with 30 minutes of social time. Beginning at 7pm, Amos King will give a presentation on the Tessel, a microcontroller that runs JavaScript:

“Bring your hardware to hack. If you have any thing that works on 3.3v we should be able to use it. We can also work off of 5V depending on how we power the Tessel, but 3.3V is safe. Bring old toys that have motors, sensors, leds. We might be able to use them. I am bringing 7 tessels and some modules plus a few fun things to play with.

“The Tessel brings the event driven callbacks of the real world to the event driven callbacks of javascript. Node compatibility and wifi on board make this device perfect for ubiquitous computing ideas to be brought to life. Have you ever wanted your toaster connected to the web? I haven't either, but there are plenty of other ideas I've had in mind. Put a ble device on your dog and have him/her tweet every time she is close to home. These are just a few ideas, but what can you come up with?

“I will share some of the things that I have done, and some background on the Tessel. Then we will dive into a hack session and see what we can come up with in small groups. I do not work for Technical Humans, but I love hardware and I love this platform.”

After the presentation, there will random drawings for three Amazon.com $100 gift cards, courtesy of Accelebrate, one of the evening's sponsors. Accelebrate offers private, on-site AngularJS training.

Meetup starts at 6pm, with 30 minutes of social time. Beginning at 6:30pm, there will be a presentation on Functional Programming in JavaScript by Brad Urani.

Functional programming is the rage, but you don't need to learn a functional language to get started doing it. In fact, JavaScript has had almost everything you need to program in a purely functional style from the beginning.

In this talk, we'll explore the basics of functional programming – higher-order functions, partial function application, lazy evaluation and persistent data structures. We'll see how a functional style helps you compose logic in a way that's clean, testable and free of certain classes of bugs. Then we'll tie it together into a purely functional style by demonstrating a clever algorithmic game solver.

Complementary sodas and sandwiches will be provided, and you're welcome to BYOB, so come hungry, come thirsty, bring your laptop and be ready to code!

We're starting the meeting 30 minutes early this month because at 8pm a fundraising event will be held in the same space. STLJS is unaffiliated with the event, but its organizers have indicated that all STLJS attendees are welcome to stick around and participate. Additional details are available on their Facebook event page:

Meetup starts at 6:30pm, with 30 minutes of social time. Beginning at 7pm, there will be a presentation on Ext JS by Mitchell Simoens.

Ext JS is an OOP JavaScript framework boasting a class-based architecture with 150 UI components, a strong data package and MVC/MVVM application structure. Ext JS is used by more than half of the Fortune 100 companies and is the leading standard for building business-centric Web applications. Mitchell will give an introductory presentation, including live examples of how to build a simple application with Ext JS.

Starting about 8:30pm, we'll move into a hacking session to experiment with the material that's been presented, and with JavaScript and Node.js in general. 

Following the presentation, there will be one random drawing for a free two-day conference pass to St. Louis SecureWorld 2014. Don't miss your chance to win!
