Data structures for frontend developers
summary
An overview of data structures used inside popular frontend libraries and frameworks, explaining why tools like React can efficiently perform partial DOM updates and how Immutable.js implements copy-on-write while staying memory- and time-efficient. The talk examines specific libraries and the special data structures they use, and shows how classic techniques from 1980s textbooks and university lectures can be applied to solve frontend problems effectively.
