Know your Javascript Engine

The document discusses how JavaScript engines have improved performance over time. It explains that early JavaScript engines in 2006 used interpreters which were slow due to overhead from boxing and unboxing values. Modern engines in 2011 use just-in-time (JIT) compilers to generate fast machine code, and techniques like inline caching (IC) and type specialization to optimize property access and e
