Can the amazing capabilities of Google's V8 Engine truly transform JavaScript into Native Code, store it as a binary file, and run it seamlessly within my software environment, across all machines?

One way to optimize your code is by utilizing the V8 snapshot feature for precompilation. However, it's important to note that even with snapshots, you still need a complete V8 environment to load them, meaning you can't achieve stand-alone native code. The only advantage here is saving on compilation time. It's worth mentioning that the quality of snapshot code may not be as high as JIT compiled code, as JIT compilers can take advantage of features like SSE2/SSE3 if they're supported, which snapshots cannot assume.
My understanding is that V8 functions solely as a just-in-time compiler, without the capability for ahead-of-time compilation.
Based on the sources I provided, JITs enable superior and more adaptable optimizations.
One potential solution could involve utilizing a .NET JavaScript/JScript compiler to generate a .NET executable, which can then be transformed into a native .exe by employing the Mono ahead-of-time compiler.
If you're looking to reach your objective, one option could be to develop a self-executing JavaScript bytecode wrapper.
An example of a tool that accomplishes this is pkg
This tool is able to generate a standalone binary executable from JavaScript code, along with its module dependencies and asset files.
The process of installation and use is straightforward:
$ npm install -g pkg
$ pkg index.js -o my-program
$ ./my-program
From what I understand, the resulting binary includes Node.js bytecode and supports cross-compilation.
On a side note, I've experimented with ncc and nexe as well. However, I found ncc only creates a self-contained JS file, while nexe gave me a Python error during usage.
