# jsjit

Experimental javascript JIT compiler

# Prerequisites

- v8 or d8

1. Get the v8 or d8 executable

    - See https://v8.dev/docs/build

2. Set the path to v8/d8 to the environment variable `$JSJIT_D8_BIN`

    - Make sure `$JSJIT_D8_BIN` points to the executable

    - e.g. Write `export JSJIT_D8_BIN=$HOME/path/to/v8/v8/out/x64.debug/d8` in `.bashrc`

# Run

At first, you have to compile js code to v8 bytecode:

```sh

./v8-bytecode-gen.py exmaples/add.js

```

Then, feed the generated bytecode to our interpreter:

```sh

cargo run examples/add.bc.json

```
