Shazam! We had a fantastic social last month and now we are "fall"ing back into the swing of things with some amazing speakers! Join us the 2nd Thursday in October at Code Fellows' new campus for a heart-stopping, death-defying, and spell-binding meetup where we'll be learning all about minding gaps and making dates good (in JavaScript, not irl)! Why are you still reading and not clicking the RSVP button?


Topic 1: Mind the Gap with React
by Ryan Florance
@ryanflorence ( | gh ryanflorence ( | website (

abstract:: By far the most difficult challenge in user interface programming is to bridge the gap between simply reading code and understanding what actually happens when it runs. React gives us a fantastic tool that helps eliminate time so we can more easily predict exactly what's going to happen.

bio:: Co-author React Router, Co-owner ( JavaScript thought-haver. Junior Developer for Life.


Topic 2: Moment.js- Creating Good Parts
by Maggie Pint
@maggiepint ( | gh maggiepint (| website (

abstract:: Did you know that the JavaScript Date object will not allow the user to differentiate between dates in month/day/year and day/month/year format? That it cannot represent time zones other than UTC and the time zone of the user’s browser? We all know that JavaScript has good parts and bad parts, and Date is definitely one of the bad parts.

Moment.js and Moment TimeZone address fundamental issues with the JavaScript Date object, creating a clean and full featured API that allows the developer to produce quality code. Let’s explore some problems that developers face with date and time in programming, and how Moment helps the developer better address these issues. In addition, let’s discuss the implementation of Moment.js, the future of the library, and how you can get involved with making a JavaScript library that creates a ‘good part’.

bio:: Maggie works in the Open Source Programs office at Microsoft, where she helps people navigate Microsoft’s OSS ecosystem both by writing code to better automate open source processes, and by advocating OSS within the organization. In the past she has been a SQL Server DBA, a full stack .NET developer, and a project manager. In her non-Microsoft open source life, she is a maintainer of Moment.js, and a frequent conference speaker advocating for open source involvement and better handling of date and time in programming.

When she is not coding, Maggie enjoys spending time with her four-year-old son, drinking too much coffee, and showing and breeding Australian Shepherds.
