kou opened a new issue, #46974: URL: https://github.com/apache/arrow/issues/46974
### Describe the enhancement requested The current implementation assumes that the JS implementation exists in `${ARROW_BUILD_ROOT}/js/`: https://github.com/apache/arrow/blob/35f8fbce0bc7d24fd84156863b57e17c6177fb9a/dev/archery/archery/integration/tester_js.py#L25-L29 `${ARROW_BUILD_ROOT}` is used by other implementations too. So it's difficult to put the JS implementation to separated directory. If we can set the JS implementation directory by an environment variable only for this purpose such as `ARROW_JS_ROOT`, we don't need to copy the JS implementation to `${ARROW_BUILD_ROOT}/js/`. ### Component(s) Integration, Archery -- This is an automated message from the Apache Git Service.
