Uber is migrating away from Buck to Bazel. One major reason is poor support for a variety of languages (Go being one big one, where fixing issues was historically slow due to a need to upstream fixes to Buck core). I haven't worked with Buck myself, but colleagues who evaluated it for JS have expressed concerns with lack of support/ecosystem there as well. In comparison, there are various Bazel rulesets for JS/Typescript, and I've had some pretty good experience w/ implementing rules myself. The Starlark docs are good. Another thing going for Bazel is its ability to embed external codebases into a build system. This mechanism allows rules to be shared among repositories in a reusable fashion.
