ArkCompiler JS Runtime
Introduction
ArkCompiler JS Runtime is the default JS runtime on OpenHarmony. It supports ECMAScript libraries and efficient container libraries. It also provides a set of native APIs for C++ and JS interaction and a variety of garbage collectors that features high performance.
For more information, see ArkCompiler JS Runtime.

Constraints
- Only the ArkCompiler bytecode files generated by ts2abc, which is the ArkCompiler JS frontend toolchain, can be run.
- Only the ES2021 standard and strict modes are supported.
- Functions cannot be dynamically created using strings, such as new Function("console.log(1);")).
Building
$./build.sh --product-name hispark_taurus_standard --build-target ark_js_host_linux_tools_packages
Available APIs
See NAPI.
Usage
For details about how to generate JS bytecodes, see Using the Toolchain.
To run bytecodes:
LD_LIBRARY_PATH=out/hispark_taurus/clang_x64/arkcompiler/ets_runtime:out/hispark_taurus/clang_x64/thirdparty/icu:prebuilts/clang/ohos/linux-x86_64/llvm/lib ./out/hispark_taurus/clang_x64/arkcompiler/ets_runtime/ark_js_vm helloworld.abc
