JSFoo Pune 2019

JSFoo Pune 2019

JSFoo is a JavaScript conference hosted by HasGeek.

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.
