Immutability and Abstractions

Dear fellow JavaScript enthusiasts!

This time we will watch two high-rated presentations from two Facebook developers. Their talks target currently-discussed topics: Immutability and Abstractions.

In Immutable User Interfaces, design technologist Lee Byron speaks about one of the greatest challenges of building a rich UI: keeping track of all that is changing, incoming touch and mouse events, new data from your servers, animations, and more. He proposes a new way to tackle this challenge that is as old as computing itself: don’t let anything change in the first place. We will learn about how to build rich and highly performant UIs without losing our sanity by leveraging immutable data and the optimization techniques it enables.

JavaScript and the React community have evolved over the years through all the ups and downs, says Cheng Lou. His talk On the Spectrum of Abstraction goes over the tools we've come to recognize, from Angular, Ember and Grunt, all the way go Gulp, Webpack, React and beyond, and captures all these in a unifying mental framework for reasoning in terms of abstraction levels, in an attempt to make sense of what is and might be happening.
