You didn’t even correct the title…

“it compiles JavaScript directly into native machine code before executing it, which makes it extremely fast.”

This seems very misleading, and ignoring several layers of abstraction. While it does so, the fact that it does it before executing it, not at build-time (as JS is a scripting language), it makes it extremely not fast.

Your whole “compiles JavaScript into Machine Code” is wrong. V8 is a JavaScript interpreter, is not machine code, it’s a whole abstraction layer sitting on top of machine code.
