The Vector type is simply a generic type for built-in JavaScript Arrays. The parameter type is the type of all of the entries of the Array. The Vector type also supports inhomogeneous arrays by using the special type `Unknown` as the argument type, but note that when computing with inhomogeneous arrays, method dispatch must be performed separately for every entry in a calculation, making all operations considerably slower than on homogeneous Vector instances.
Note also that arithmetic operations on nested Vectors, e.g. `Vector(Vector(NumberT))` are defined so as to interpret such entities as ordinary matrices, represented in row-major format (i.e., the component `Vector(NumberT)` items of such an entity are the _rows_ of the matrix.

We use [mocha](https://mochajs.org/) as the test framework, as it is
the tool used by mathjs and we would like to make tests as similar
as possible. However, to tighten the linkage between source code and
tests, we adopt a somewhat different file organization: unit tests
for a given source file `blah/foo.js` are in `blah/__test__/foo.spec.js`.
To run all unit tests, execute the script `pnpm test`.
