Is it really possible, with Google's V8 Engine, to compile JavaScript into Native Code, save it as a binary file, and execute it whenever I want through my software envorinment, on any machine?

V8 JavaScript engine is an open source JavaScript and WebAssembly engine that compiles JavaScript to optimized machine code before execution.
V8 is Google's open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node. js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors.
It is certainly theoretically possible; however, a static compilation of JavaScript would need a very heavyweight runtime to support all of its features (such as dynamic typing and eval).
You can use the V8 snapshot functionality to precompile the code. This still means that you have to have a full version of V8 running to load the snapshot (i.e., you don't get stand-alone native code, it needs to run inside the V8 VM), so all you save is the compilation time. Also, the quality of snapshot code isn't necessarily as good as JIT'ed code because JIT code can use, e.g., SSE2/SSE3 if it's available, which snapshots can't assume.
