JavaScript Compilation Techniques - Wasn't JavaScript Supposed to Be Slow?

Explore advanced JavaScript compilation techniques and performance optimizations in this insightful conference talk. Delve into topics such as static scope, local eval, basic unboxing, heap management, mark and sweep algorithms, generational garbage collection, inline caching, and hidden classes. Gain a deeper understanding of how modern JavaScript engines work to improve execution speed and efficiency, challenging the notion that JavaScript is inherently slow.
