## CSSinJS Unique Value Proposition and Future

All you wanted to know about the reasoning behind CSS-in-JS, but been afraid to ask. Oleg went through a long journey, investigating the field, and building lot's of tools for styling applications via JavaScript, and gladly help navigating your way into this journey.

About Oleg @oleg008

I have been working on web UIs over a decade when I realized there are 2 major challenges in front-end engineering: understanding the state and styling its representation. While the first task has become much easier with unidirectional data flow, components styling is still painful. To change that I started a project called JSS back in 2014 and didn't stop learning and improving it since then.

## Jest Can Do Whaaat?

Jest is React’s best testing companion. It also brought several concepts to mainstream JavaScript testing: zero configuration, first-class mocking, and snapshots. With the rapid release of speed improvements, it’s easy to miss a new useful feature. I will present some lesser-known possibilities of recent Jest versions I’ve learned during experimenting, reading (and writing) the docs, and browsing the code.

## The Effect of React on Web Standards

Since inception React has solved problems from first principles, choosing to create the best possible product instead of relying on what was possible with already existent technology. In order to achieve this, the React team has invented new languages and paradigms such as JSX, the React component model and unidirectional data flow.

This talk will review these inventions and the supporting changes proposed to web specifications.
