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.

Crisp talk
Technical level:
Intermediate
Performance today has become a prime concern of apps as who doesn’t love a fast app. In today’s world which is full of distractions, there can be nothing more difficult than engaging the user with a slow app. If your app is slow, gradually user will get frustrated and leave it. As developers, we are aware mostly about major factors affecting an app’s performance, like too many scripts requests etc.. but there are other factors too which can help in further boosting the performance like code-splitting/tree-shaking. This talk aims towards sharing what these concepts are and with the help of case studies attempt to provide a data insight into what effect these factors can have on your app’s performance.
