what do people make with this?

VIBE 1

Build a domain-specific language that compiles expressions to fast machine code from JavaScript.

VIBE 2

Create a runtime math expression evaluator using LLVM instructions like createAdd and createMul.

VIBE 3

Prototype a shader or query compiler that needs compiled-code speed with JavaScript control logic.

how do i run it?

Difficulty · hard time til it works · 1h+

Requires LLVM 3.2 installed on the machine and Node-FFI to bridge compiled code to JavaScript.

No license info given in the explanation.

prompts (copy fr)

prompt 1

Walk me through the Kaleidoscope example and how it compiles math expressions using this library.

prompt 2

Show me how to use createAdd, createMul, and createLoad to build a simple compiled function.

prompt 3

What are the memory management limitations of this library, and how should I design around them?
