JSFoo 2016

Tackling speed and performance for JavaScript

##About JSFoo

JSFoo is India’s premier JavaScript conference. We launched JSFoo in 2011 as India’s first JavaScript conference. The JS community in India has grown phenomenally since. JavaScript now pervades every aspect of web development – browsers, apps, front-end, backend, mobile, and IoT.

##JSFoo 2016: Theme

Over the last few years, JavaScript has evolved to become the centerpiece of a complex web stack. Today, it is a prime subject of the obsession that lies with performance and speed. How can you get pages to load faster? How do you work with browser constraints to enhance speed? How do you measure performance? What actually is performance? In what ways do faster response times influence your architecture choices and plans? How is this new focus on faster page loads and apps working offline influencing the development of front-ends and backends as well as server side JS?

The theme for the 2016 edition is tackling speed and performance for JavaScript.

We are inviting full talks (40 mins), crisp talks (15 mins + 5 mins Q&A), and 3-6 hour long (hands-on) workshops from practitioners on the overall theme of speed and performance, including the following topics:

  • Architecting for performance – case studies on how you got faster response times
  • Best practices: debugging and profiling on the web, measuring performance
  • Handling large volumes of data in the browser
  • Building and deploying web apps eg webpack, travis
  • Modern web technology: Angular 2, React
  • Universal JavaScript: meteor js
  • Progressive Web Apps
  • JS off the web – raspberry pi, IoT
  • The cutting edge: elm

This year, JSFoo will feature two days of talks on JavaScript (15-16 September) and a single day of talks on design (17 September) at Meta Refresh (call for proposals will open shortly).

Guidelines for submission

Every proposal MUST be accompanied by:

  • A three minute preview video where the proposer gives an elevator pitch about the talk.
  • Detailed outline of the talk – either in the form of draft slides, mind map and/or textual description.
  • If you are proposing to speak on a topic where the code is not open-sourced yet, the editorial panel will consider your proposal only if the code is made open-source at least three weeks before the conference.

Without the above information, your proposal will not be considered for review.

If you are submitting a Workshop Proposal, you must clearly state:

  • Background knowledge that participants must possess in order to attend your workshop.
  • Details and links to software / packages which participants must install before coming to the workshop.
  • Laptop configuration.
  • Links to background reading material and GitHub repos.
  • Duration of the workshop.
  • Maximum number of participants who can attend your workshop.
  • Instructor’s past experience with conducting workshops.

There is only one speaker per session. Workshops can have two or more instructors.

Entry is free for selected speakers.

Due to budgetary constraints, we prefer speakers closer to home. But if we think you stand out, we’ll provide a grant to cover part of your travel and accommodation to Bangalore. Grants are limited and are made available to speakers delivering full sessions (40 minutes or longer) only.

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 for it to be available under a permissive open source licence. If your software is commercially licensed or available under a combination of commercial and restrictive open source licences (such as the various forms of the GPL), please consider picking up a sponsorship. We recognise 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.

Important dates:

Deadline for submitting proposals: 29 August 2015
Conference dates: 15-16 September

JSFoo will be held at the MLR Convention Centre, J P Nagar.

The Economics of JavaScript

Submitted Aug 17, 2016

A beginner breaks, repeats, makes mistakes, and learn to program. By the time, she becomes a very good developer, she believes everything starts and ends in her work, her codes, and her philosophies. As she matures, she realizes that her codes and her works are mere parts of a bigger picture - a tiny role that make other people, and systems work. The day she realizes that her impact, even though small, has to be the best and meaningful, is the day she cares about everything else than just her work.


JavaScript has won the desktop. It is beginning to win the mobile and will do so sooner than you can anticipate. Businesses have realized the importance of JavaScript, are investing in it pretty heavily. It is no longer surprising that JavaScript is on to a path of World Domination.

My talk will be about the economics of JavaScript for developers, managers, and businesses. As a JavaScript developer, why is it important to understand the factors that implicate and impact your work - be it cost, time or acceptance by the other facades of running a business, company, a startup or a simple app.

I’ll be referencing our recent work with Aditya Birla’s http://abof.com and how we made it the fasted eCommerce site (mobile/desktop) in India. You should try it, it works pretty well even on a bad 3G connection on an OK mobile phone.

I will also get a bit technical and I might blurb terms such as - Isomorphic JavaScript, Immutable Codes, Progressive Web apps, Server Side Rendering of Frontend Codes, React, Redux, Helmet, build automation, gulp, webpack, component based styles and designs, perpetual designs, et al.

In fact, I’ll also say some money numbers in relations to features, browsers and how to win over your clients, bosses to take the right decision with your work - JavaScript codes, CSS/HTML Markups.

I’ll try my best to add fuel to your JavaScript development rocket on how can you blast your career faster, better, and position yourself in your company, with clients as a much better, matured, dependable and high-value person.

Speaker bio

I believe in simplicity, minimalism, and have an ardent willingness to push the bounds, envisioning the betterment of usable and practical solutions.
