JSFoo 2014

JavaScript as the centerpiece of a complex web stack

In 2011, Node.js put JavaScript firmly in the backend, making JavaScript developers productive at both ends of the stack, and making it possible for business logic to finally be moved into JavaScript.

In 2012, AngularJS made us think about moving business logic completely into the client-side as an actually sensible idea. Meteor give that idea two thumbs up.

In 2013, we went wild thinking of all the possibilities. JavaScript phones! Robots!

In 2014, it’s time for some sobering up. The backends we built over a decade in Ruby and Python aren’t going away. New languages like Go and Hack are tantalising us with new possibilities. Our applications are increasingly distributed, often involving third party APIs. In such a scenario, where does your business logic reside?

In 2014, JavaScript is no longer a toothless child or a rebellious teenager that wants to do everything itself. JSFoo 2014 is about working with JavaScript as the centerpiece of a complex web stack.

Format

This year’s edition spans four days, with two days of workshops and two days of conference. All days feature a single track. We invite proposals for:

  • Full-length 40 minute talks
  • A crisp 15-minute presentation
  • Sponsored sessions, 40 minute duration
  • Flash talks of 5 minutes duration. Submissions for flash talks will be accepted during the event
  • Three hour workshops where everybody gets their laptop out and follows along

Criteria to submit

You must be a practising web developer or designer, and must be able to show how your own work has advanced the state of the web in the past year. You are expected to present original work that your peers — this event’s audience — recognise as being notable enough to deserve a stage.

If you are excited about someone’s work and believe it deserves wider recognition, we recommend you contact them and ask them to submit a proposal.

Selection Process

Voting is open to attendees who have purchased event tickets. If there is a proposal you find notable, please vote for it and leave a comment to initiate discussions. Your vote will be reflected immediately, but will be counted towards selections only if you purchase a ticket.

Proposers must submit presentation drafts as part of the selection process to ensure that the talk is in line with the original proposal, and to help the editorial panel build a strong line-up for the event.

There is only one speaker per session. Entry is free for selected speakers. HasGeek will cover your travel to and accommodation in Bangalore from anywhere in the world for speakers delivering full sessions (30 minutes or longer). As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. If you are able to raise support for your trip, we will count that as speaker travel sponsorship.

If your proposal is not accepted, you can buy a ticket at the same rate as was available on the day you proposed. We’ll send you a code.

Commitment to Open Source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Learning JS concepts/techniques by implementing jQuery

Submitted Aug 25, 2014

This is a “Re-implement and Learn” workshop.

The aim of this workshop is to have a list of some concepts and common techniques used in JavaScript and then learn them by implementing parts of an existing library. For this session, we’ll be implementing features of jQuery to understand JavaScript more closely.

Understanding the concepts implemented in this workshop will enable you to write code which is:

  1. More Clean
  2. More Manageable
  3. More Testable

Outline

The workshop will be around understanding following concepts and techniques by actually implementing each of them one by one:

Following point follow the syntax: <Concept we’ll learn> - <What we’ll implement>

  1. Prototypes: jQuery core

  2. Use of ‘this’: jQuery core

  3. Callbacks: $.each

  4. Chaining: $.css

  5. Function overloading: $.css (getter only)

  6. Function context: $.bind

  7. Partials: $.ajax and $.json

  8. Apply what we learnt: $.debounce

Note: This workshop isn’t targeted towards implementing jQuery completely and won’t focus on its cross-browser feature implementations. Only implementing functionalities required to understand the above mentioned concepts will be the focus of this workshop.

Requirements

Good news! You don’t need anything particular installed on your system. If you have a descent browser (no IE) and a code editor on your machine, we should be good. No need to install node, grunt etc.
