A Trip to the Zoo - SpiderMonkey, SquirrelFish, Nashorn, V8

Explore the inner workings of JavaScript engines and discover why they are incredibly fast in this conference talk from JSConf EU 2015. Delve into fundamental concepts such as abstract syntax trees, opcodes, and just-in-time compilation. Learn how JavaScript code can achieve performance levels comparable to native C++ code through advanced optimization techniques. Examine hidden classes, ahead-of-time compilation, and single instruction multiple data computations, understanding how these methods can significantly boost code performance when applied correctly. Gain insights into the mechanics of popular JavaScript engines like SpiderMonkey (Firefox), SquirrelFish/Nitro (Safari), Nashorn (JVM), and V8 (Chrome), and discover practical examples for writing faster, more efficient code.
