🚀 Which part of V8’s process do you think has the biggest impact on performance?
- Ignition Interpreter
- TurboFan Optimizing Compiler
- Garbage & Memory
- Object Shapes & Hidden Classes
Ever wondered what really happens when your JavaScript runs in Chrome or Node.js?
V8 doesn’t just interpret your code — it compiles, optimizes, and turbocharges it for near-native speed.
In my latest article, I break down how V8 works step-by-step — from bytecode execution to machine code optimization.

I’d probably go with TurboFan — it feels like that’s where the real speed boost happens once the code’s “warmed up.”
But honestly, all these pieces work together, so it’s hard to pick just one. Curious to see what others think.
Hmm… maybe Object Shapes & Hidden Classes? I’ve heard they can make a big difference, but I’m not entirely sure. V8 seems super complex!
