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.

How ECMAScript6 can change your life

Submitted Aug 22, 2016

ECMAScript 2015 (ECMAScript6) is the current version of the ECMAScript Language Specification standard. It has come up with many new features and is having a varied impact on the lives of Javascript developers. This session will cover those new things in ECMAScript6 and the need for the web developers to upgrade their skills to ES6 with the plan of launch of ES7 and ES8 already in place. From providing syntatic sugar to eliminating dead code using “Tree Shaking”, all that ES6 does, will be covered in this talk.

Anyone having basic knowledge of HTML and CSS and intermediate knowledge of JavaScript can attend this session. From this Live Demo Oriented Session, the attendees can expect to enhance their knowledge of ECMAScript6 and clear the doubts they would be having related to the technology. With the advancements in technology happening with each passing day, it is high time that the web developers catch up with the concepts of ES6 and understand the difference it can bring to their coding.


The talk will cover the new features in ES6 and the change that ES6 can bring to your life. Few, out of the list of topics, that will be covered are listed below:

• New Keywords
• Spread Operator
• Default Function Parameters
• Arrow Functions
• Classes
• Modules
• Promises
• Typed Arrays
• New Built-In Methods
• Adding the ES6 Flavour to your IDE
• Better Support for ES6 in IDEs
• Dead Code Elimination in ES6
• Performance impact using ES6
• Road Ahead – ES7 and ES8
• And much more…

A glimpse of this can been seen in the preview video and the slides attached.
