@endo/common v1.2.7

@endo/common

A collection of common low level utilities.

Each of the utilities in this packages

• are low level in the sense of not depending on anything higher level than ses, @endo/eventual-send, and @endo/promise-kit. Many depend on nothing beyond plain old JavaScript.
• highly reusable, i.e., potentially useful many places.
• sufficiently general that it would be awkward to import from a more specialized package.
• can be explained and motivated without much external knowledge.

Each utility is in its own top-level source file, named after the main export of that utility. (This is often that file's only export.) The package.json also lists each as a distinct "export":. There is no index.js file that rolls them together. Thus, each importer must do a deep import of exactly the export it needs. Some implementations (bundlers, packagers) can thus do tree-shaking, omitted code that isn't reachable by imports.

Currently there are no src/something.js files. The only source files that would go in src/ are those that do not represent separately exported utilities.

Generally each utility also has its own test file. (An exception is that make-iterator.js is indirectly but adequately tested by test-make-array-iterator.js).

See the doc-comments within the source file of each utility for documentation of that utility. Sometimes the associated test files also serve as informative examples.
