This is a Typescript solution to the TestDouble Bank OCR Kata.
After a yarn install,
Run the demo with yarn demo
Run the tests with yarn test (or yarn dev for watch mode)
note: This was built on Node v10.16.1 and not tested with earlier versions
I stopped work at (roughly) three hours, although this was split across 2 days.
This solution completes user stories 1, 2, and 3. Some preliminary work for story 4 is included, but not reflected in the demo or the tests.
My overall next steps would be:
- Complete user story 4 (ambiguous account number matching)
- Check test coverage
- Create CLI command & JS module exports
- Add documentation
Otherwise - a good deal of the code for parsing each line comes down to manipulating matrices (mostly in parseLine.js). This was new territory for me and I would be interested in abstracting what I have here into something more generic. This would make reasoning about parseLine easier, and also allow for an easy way to re-create the "OCR" characters from a string of digits.
This was fun, thank you!
