At work, we needed a library to calculate the vehicle tax for a vehicle, and as far as I could gather at the time one did not exist. So I created a library that could be used to calculate road tax for most cars and vans.

Tech Used

• Development: JavaScript, no reliance on Node or the browser, developed with ES Modules and transpiled with microbundle
• Testing: Uses ESLint for linting and Jest to run test suites
• CI: Uses Microsoft Azure Pipelines to run tests for PRs and master commits
