JSFoo is the annual JavaScript conference hosted by HasGeek. The Pune edition is the second edition (JSFoo in Pune in 2012, and ReactFoo in January 2018).
HasGeek launched JSFoo in 2011 as India’s first JavaScript conference. The JS community in India has grown phenomenally since then. JavaScript now prevades every aspect of web development - browsers, apps, front-end, back-end, mobile and IoT, and there’s always scope to understand new ideas and solutions. The conference explores new ideas, implementing innovative solutions, and learning from experiences, especially negative ones.

Section:
Full talk
Technical level:
Intermediate
If you are a web developer, you must have worked on a web app that was.. slow. It’s your job to fix it and you want to poke around the internals, see which function takes the longest amount of time and what you can optimise. So you load up your app on Chrome and open the performance profiler tab. You record a few interaction.BOOM! you are presented with a screen full of colorful visualizations! And now you go to the Chrome profiler documentation and sigh..
This talk is designed to teach you the layout of the Chrome profiling tab. We will look at all the details of information that it captures, looking at call stacks, frame times and markers. I will bring examples from my experience to show you how profiling can debug performance bottlenecks and help you make your web apps behave faster.
Outline
- Intro performance profiling in Chrome - 2 mins
- Walkthrough of the UI - 5 mins
- Basic example profile and walkthrough - 10 mins
- Examples of performance bottlenecks fixed - 20 mins

- Page freezing incidents
- Few more..
