JSFoo 2013

All about being creative with JavaScript

(Skip ahead to session proposals)

About JSFoo

JSFoo is India’s only national JavaScript conference. The first season of JSFoo featured editions in Bangalore, Pune and Chennai between Oct 2011 and Feb 2012. The second edition in Bangalore in Oct 2012 was based on the theme “JavaScript Everywhere” – featuring JavaScript on web servers, embedded in robots, as a cross-platform language for mobile, and in its original home, the browser.

##JSFoo 2013
The theme for JSFoo 2013 is original creations with JavaScript. Showcase innovative work done with JavaScript – if you have created something at work or outside your work commitments, with or without a business model in sight, something you’ve done for the love of seeing it come to life in front of your eyes, JSFoo is the place to talk about it!

Talks which demonstrate innovation at either a technical or “best practice” level will be given preference. Your creation does not necessarily have to be in production, but we will insist on it being something more significant than a cool ten-line function you came up with (unless that function allowed you to control sharks fitted with lasers or something).

We are also accepting high quality talk and workshop proposals on JS frameworks, libraries and tools. These proposals have to provide clear objectives and take-aways for practising JavaScript developers.

JSFoo 2013 is a single-track event. We invite proposals for:

  • full-length 40-minute proposal
  • a crisp 15-minute presentation
  • sponsored sessions, 40 minute duration
  • flash talks of 5 minutes duration. Submissions for flash talks will be opened one week before the event
  • Hands-on sessions ranging from two to six hours on JS libraries, frameworks and tools. These proposals will be categorized as workshops

Commitment to open source

HasGeek believes in open source as the binding force of our community. If you are describing a piece of technology, 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.

Speaking submissions

You can submit a proposal to speak at JSFoo 2013 via the submission funnel below. Please describe your proposal in as much detail as possible. Detail is important if you’d like to be voted up into the schedule. In particular, we want to hear why you are the best person to be delivering a talk on your proposed topic. Provide links to previous talks and presentations you’ve done. This will help attendees and the programme committee in evaluating your proposal.
Making a funnel submission does not guarantee final selection.

##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. Proposals will also be evaluated by a program committee consisting of:

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 program committee build a strong line-up for the event.

There is only one speaker per session. Attendance is free for selected speakers. HasGeek will cover your travel to and accommodation in Bangalore from anywhere in the world. 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.

Tickets: http://jsfoo.doattend.com

Website: https://jsfoo.in/2013


The program committee will announce the first round of selected proposals by 15th August and a second round by 2nd September. We will finalize the schedule by 7th September. The funnel will close on 25th August. The event is on 20th and 21st September 2013.

Coffee for “The Language of the Web”

Submitted Aug 26, 2013

• Do you want to avoid the pitfalls in JavaScript during development cycle itself?

• Do you want to enforce your team to follow a Standard and/or Best practices in JavaScript development?

Get on to CoffeeScript!

This presentation introduces you to CoffeeScript, to prevent the usage of bad parts in JavaScript programming. Also have a structured, readable and maintainable JavaScript application.


JavaScript is “The Language of Web”, winning the race against VB-Script, Java (Applets) etc.
JavaScript sustained the race, because it interacts better with the DOM APIs, than other languages. Today, every browser in the world supports JavaScript!

However, it is forgotten that JavaScript is a programming language, with a very good Object Oriented (OOP) and Functional programming model at its heart.
In addition, the learning curve for JS is very short and quick - within minutes, if you are familiar with programming languages; couple of hours, if you are a new programmer.

There are many more pros in similar lines. But the same good parts eventually created bad JavaScript programs.

What are the pitfalls that we are talking about?

  1. No structured programming.

  2. OOP is not utilized properly.

  3. Spaghetti type code, even after using JQuery like libraries.

  4. Style guide does not exist for most JS developers.

  5. Lack of proper knowledge about ‘scope’ and ‘prototype’ creates fatal issues.

  6. Similarly, lack of interest or knowledge on optimizing JS code.

How to alleviate?

• Write Maintainable, Organized & Optimized code while sticking to the Good parts of JavaScript.

• Build JavaScript application in Object Oriented mechanism than just writing DOM events.

• Don’t use JavaScript, use another language! …?

Now, let us have some Coffee - CoffeeScript!

CoffeeScript elegantly expresses and accentuates the Good parts of JS and smoothens out some of the Bad parts, all via the Ruby way of programming. CoffeeScript (CS) can indeed turn out to be a rescuer for a JS developer time and again. This presentation will discuss and highlight the necessity and the benefits of CoffeeScript, with illustrated example.


This talk is for all levels of JavaScript developers. Since the talk is about CoffeeScript, to avoid the bad parts of JavaScript, UI Developer at any level can attend this session

Speaker bio
