# Using the Toolchain The ARK front-end tools use the command line interaction mode and convert JS code into ARK bytecodes that can run on ARK runtime. The toolchain supports Windows, Linux, and macOS. ## JS Bytecode Compiler Front-end tools, converting JS source code into ARK bytecode, can be built by specifying the `--build-target` with `ark_ts2abc`. Build tools: ``` $ $ ./build.sh --product-name rk3568 --build-target ark_ts2abc_build ``` Install `node` and `npm`, then use tools: ``` $ cd out/rk3568/clang_x64/arkcompiler/ets_frontend/build $ npm install $ node --expose-gc src/index.js [option] file.js ```
