Combined with the ace-ets2bundle component, it supports converting ETS files into ARK bytecode files. 13 14For more information, see: [ARK Runtime Subsystem](https://gitee.com/openharmony/docs/blob/master/en/readme/ARK-Runtime-Subsystem.md). 15 16**ets_frontend architecture** 17 18 19 20## Directory Structure<a name="section161941989596"></a> 21 22``` 23/arkcompiler/ets_frontend/ 24├── test262 # scripts for configuration and running Test262 25├── testTs # system test cases 26├── es2panda 27 ├── aot # logical entry 28 ├── binder # info binding 29 ├── compiler # compiling logic 30 ├── ir # Bytecode generation 31 ├── lexer # lexical analysis 32 ├── parser # syntax parsing, AST generation 33 ├── scripts # script directory 34 ├── test # test directory 35 ├── typescript # typescript support 36 └── util # tool directory 37├── ts2panda 38 ├── scripts # dependency scripts 39 ├── src # source code directory 40 ├── templates # ruby templates 41 ├── tests # unit test cases 42 ├── tools # tools provided by ts2abc 43 └── ts2abc # ts2abc source code 44 45``` 46 47## Build<a name="section0446154755015"></a> 48 49ets_frontend uses the command line interaction mode and converts JS code into ARK bytecode files that can be run on an ARK runtime system. ets_frontend supports Windows, Linux, and macOS. Front-end tools, converting JS source code into ARK bytecode, can be built by specifying the `--build-target` with `ets_frontend_build` on Linux. 50 51``` 52$ ./build.sh --product-name
