See https://github.com/stdlib-js/stdlib/tree/4b1d77d2bd001d5970ce93230765a579fb41349d/lib/node_modules/%40stdlib/array/bool#booleanarrayprototypeslice-start-end- for what is excepted in terms of documentation. Additionally, this documentation should be inserted such that methods are listed in alphabetical order.

You are missing a separate benchmark file which evaluates performance as a function of array length. E.g., https://github.com/stdlib-js/stdlib/blob/4b1d77d2bd001d5970ce93230765a579fb41349d/lib/node_modules/%40stdlib/array/bool/benchmark/benchmark.slice.length.js

Should accept negative integers, not just nonnegative integers.

You don't need this temporary array. As in
, you can create a new instance and then copy elements directly to the target array DataView buffer.

Please follow stdlib spacing conventions consistently throughout this file.

Your tests should essentially follow the same structure as https://github.com/stdlib-js/stdlib/blob/4b1d77d2bd001d5970ce93230765a579fb41349d/lib/node_modules/%40stdlib/array/bool/test/test.slice.js. For every set of tests in that package, I would expect to see similar tests in this package.
