There is no way to use toBeCloseTo for objects.

I try to add new tests, but I fail.

I tried to follow the example from the official documentation, https://jestjs.io/docs/en/expect.html#expectextendmatchers, but it does not work.

Similarly, https://stackoverflow.com/questions/43667085/extending-third-party-module-that-is-globally-exposed looks close, but I after expect('str').myMatcher('str') I get an error: Expected 2 arguments, but got 1. An argument for 'expected' was not provided..

This is a longer example that might work, jestjs/jest#8295 and https://stackoverflow.com/questions/45743548/custom-matcher-in-jest, but didn't test + understand it even less than the previous example.

There were some changes in the interfaces - maybe it is about that styled-components/jest-styled-components#270 ?

Both fromLighter and fromDenser in Ops.ts seem to be the same function.

(An idea💡)

The idea is to create Vectors and operator with types, e.g.

Vector<[x, y, pol, dir]> or operator Operator<[spin, spin], [spin, spin]>

Thay way, it would be possible to check types at the TypeScript level. It seems that in plain TS the operations are clunky, but it is possible to use:

I didn't know how to approach it, as some operations (e.g. partialDot) make the type dependent on values.

Also, for dimensions - should be also incorporate basis?
