I recently attended a tech conference ReactFoo in Delhi. So I wanted to share with everyone what I learnt from the talks. There were numerous talks given, however I am just sharing the ones I connected to most.
Below are the sessions with brief explanations
React Internals — How understanding React implementation can help us make better apps
The talk was given by @ankit-muchhala . I loved how he explained about the internals of react. I learnt in depth how components are rendered and what are the steps that it goes through during the whole process, including understanding in details about the component lifecycle. I also learnt about the complexity of diffing algorithm during the rendering phase and how react uses heuristic diffing algorithm to optimise rendering performance.

Create your own Custom Async Renderer with diffing in Web Worker
The talk was given by Aziz Khambati (@azizhk110). He created his own async library and discussed about what he learnt while making it. Some of the highlights were the benefits of async rendering and how it improves the speed and perception of render. He also mentioned react fibre and its benefits and the future of react.

Why we should use React Canvas
The talk was given by Arwa Lokhandwala (@Arwa Lokhandwala). She talked about how she improved performance for booking seats using React canvas in BookMyShow. I loved the drastic improvement that was evident after using canvas especially when she showed demo clearly showing the performance improvement.

Cleartrip’s reactive journey from 3 to 0.2s using Apollo GraphQL
The talk was given by Eesh Tyagi. He talked how they migrated old legacy code to React. However they faced performance issues due to the huge data logic in the client side leading to increase in file size. So they introduced GraphQl in the server layer to handle the data transformation in the app. Basically the client is only talking to the GraphQl layer. All data from the API is maintained by it. I loved the idea behind it.

Piggybacking your WebVR/AR experiences with React
The talk was given by Shivang Shekhar (@Shivank Shekhar). He talked about the power of AR/VR in web and native. He has shown us a way on how we can utilise the technology to implement powerful prototypes using 3D scenes by using libraries like Aframe, React 360 and various other libraries. He also discussed the pros and cons of each which gave us a better insight on which library to choose depending on our requirement.

Deploying with confidence
The talk was given by Vaibhav Lokhande (@vaibhav7779). He talked about how they migrated their legacy code to React and the challenges they faced during the migration process and how they utilised the power of Test Driven Development to maintain their application. He also discussed the infra used to maintain the application which was really helpful.

Conclusion
All the talks definitely boosted my thrust for knowledge and helped me understand how people are solving different problems at different scale.
This reminds of a proverb I related to after googling it :P
In vain have you
acquired knowledge
if you have not
imparted it to others.
