Research direction

Start with ci/scripts/js_build.sh and measure its current integration-build time on the documented command. Inspect whether it invokes multiple TypeScript compiler configurations or versions and linting, then establish which steps are required for integration tests; done means a slimmer build that preserves those tests and improves the baseline timing.

Description

Type: enhancement
Describe the enhancement requested

The JavaScript build in the integration tests is a bit slow. Here on a 12-core CPU:

# time /arrow/ci/scripts/js_build.sh /arrow /build
[...]

real	1m8.027s
user	8m26.377s
sys	0m55.688s

I don't understand much of what it is doing, but it seems it may be compiling the TypeScript sources with several different compiler options and/or versions, and also linting the sources. Given that this is the Integration build, the build could probably be slimmed down.
