JSFoo 2015

The future of JavaScript

JSFoo is India’s premier JavaScript conference. This year is the fifth edition.

The theme for the 2015 edition is the future of JavaScript.

We are looking for talks and workshops from academics and practitioners who are at the cutting edge of developments in JavaScript.

We want to hear all about:

  • Advances in browser JavaScript
  • JavaScript in hardware
  • Functional JavaScript
  • Cutting edge developments, including original work
  • ES6

Editorial panel

  • Santosh Rajan, founder Geekskool
  • Shwetank Dixit, Extensions Program Manager and Web Evangelist, Opera Software
  • Sindhu S, Recurse Center alumni
  • Zainab Bawa, editorial coordinator, co-founder at HasGeek

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.

Workshops

If you are interested in conducting a hands-on session on any of the topics falling under the themes described above, please submit a proposal under the workshops section. We also need you to tell us about your past experience in teaching and/or conducting workshops.

BOF sessions

If you are interested in doing an unconference during the breakout sessions, propose a topic which will be of interest to the community.

Important dates:

Deadline for submitting proposals: 31 July 2015
Conference dates: 18-19 September
Workshops: 15, 16, 17 and 20 September

JavaScript for Competitive Programming

Submitted Jul 12, 2015

To explain the optimizations required to be able to use JavaScript for competitive programming and be able to solve them in the given amount of time without being victim of getting a timeout or insufficient memory, and using those optimizations as an advantage when building web applications.

Outline

Competitive programming requires lots of Data Structures / Algorithm knowledge to be able to perform efficiently. Though this knowledge is helpful, there are certain optimizations that can be done in the language(JavaScript) itself that would allow the program to be executed faster. These optimizations can be done efficiently if we get an idea of ‘behind-the-scene’ execution of our program.

JavaScript lacks in two main areas which(as of now) makes it unfavourable for competitive programming:

1.Speed - Includes programs like calculating 25000th prime number which is around 5x times slower in comparison to c,c++ using the same algorithm.

2.Memory - Includes programs like calculating factorial of a big number(say 1000) while in JavaScript you get ‘infinity’ for factorial of any number above 170 because it exceeds the number limit.

The talk will be focused on discussing these limitations and ways to overcome them, thus making JavaScript a suitable choice for Competitive programming.

Requirements

Moderate level knowledge of JavaScript
Basic knowledge of algorithm and data structures.

Speaker bio

I work as a Principal Engineer at Cuelogic Technologies and have been into full stack JavaScript development since last 3 years. I like participating in competitive programming and have been an active competitor in hackerrank.com. I also like contributing into open source projects and have been devoting my spare time in github and other open source communities.
