A from-scratch experimental ahead-of-time JS engine

Porffor is a unique JS engine/compiler/runtime, compiling JS code to
WebAssembly or native ahead-of-time.
It is seriously limited for now; intended for research, not serious
use!

Wasm compilation

Porffor's WebAssembly output is much faster and smaller compared to
existing JS -> Wasm projects. This is because Porffor compiles JS AOT
instead of bundling an interpreter.

  * Wasm size: 32x smaller than Javy (~1.3MB -> ~40KB)
  * Wasm perf: 18x faster than Javy (~70m -> ~4m)

Native compilation

Due to compiling JS ahead-of-time, Porffor can compile to real native
binaries without just packaging a runtime like existing solutions.
This leads to:

  * Binary sizes over 1000x smaller (~90MB -> <50KB)
  * Memory usage over 40x less (~50MB -> ~1MB)
  * Performance up to 3x faster

Plus...

Porffor is safe as it compiles to Wasm (and then native). It is also
written in a memory safe language (JS).

Porffor is written from the ground-up with AOT in mind instead of
being based on any existing JS engine. The only dependency is a JS
parser.

Porffor supports TypeScript input, no clunky transpiler step needed:
just feed it a TS file.

Playground You can try Porffor here online or locally with npm i -g
porffor@latest && porf
