"Cursors Illustrated: Collaborative sketching" by Ryan Dy and Marlena Compton

Sketches have a unique power to convey complicated ideas quickly between people. This talk will explore the functional programming concept of cursors, through the lens of sketchnoting. Cursors, immutability and React.js will provide the backdrop for an illustration of how collaborative drawing can illuminate and bring shared understanding to deep technical topics. The mainstreaming of functional programming is happening with the adoption of React.js, a framework that encourages the use of immutable data. Cursors, a concept from the Clojure framework OM, are a way to work with immutable data in javascript. React.js encourages a one way data flow pattern for building web applications called Flux. Cursors provide a mechanism for this. The audience will be given an intro to sketching with basic shapes before the deep dive commences with a review of the concept of immutable data and why React.js encourages immutable data for building web applications. Cursors will be introduced as a way to work with immutable data in javascript followed by an example of how to use them in React.js. Takeaways will be an understanding of why immutability and cursors are important for building web apps with React.js and an understanding of how sketching can make advanced ideas and concepts more approachable for team discussion.
