The JavaScript Engine Deep Dive.

Understanding memory management, heap vs stack, and how V8 handles Primitive and Non-Primitive data types for high-performance execution.

🚀How We Implemented It

This article breaks down the internal workings of the V8 engine, exploring how the parser, interpreter (Ignition), and optimizing compiler (TurboFan) work together to execute JavaScript at near-native speeds.

⚙️The Development Process

I analyzed the memory allocation strategies, comparing stack and heap usage, and created benchmarks to demonstrate the performance impact of hidden classes and inline caching in modern JavaScript applications.
