Webassembly & Javascript: Building fast-er web applications

Submitted by Anirvann Das (@anirvann) on Sunday, 1 September 2019

Section: Crisp talk (20 mins) Technical level: Advanced Status: Awaiting details


The session is meant for users to take advantage of webassembly with browser as a virtual machine. The final goal would be to achieve fast, performant web applications.
I would be presenting a use case where the web application has become faster after integrating webassembly.


  • What is webassembly
  • How to generate byte code
  • A use case; to showcase how webassembly can make web applications faster.

Speaker bio

Having integrated webassembly, into our dashboards webapp, we realised the power of running high-level languages in parallel with javascript. And I feel this should be showcased to the web developers community so people can leverage the new technologies as and when needed.

    Thanks for the submission, Anirvann.

    How will this proposal be different from an introductory talk about Webassembly? The details are too thin. Explain the use case to show us the depth of this talk.

    The deadline for submitting these details is 9 September.

    Hi Zainab,

    Thank you for getting back to me.
    You are right, the talk would have been an introductory walkthrough about web assembly and a demo(using my company’s internal site) on how tweaks helped us improve our web app performance. Points I was targetting to cover. * Moving code from main thread to web workers * Using compiled C code to aggregate the ~1million records.

    However I was busy participating in a hackathon and have not been able to prepare the slides. Ill try preparing the entire presentation and get ready for a forthcoming JSFoo.
