Build Your Own Spreadsheet

Build Your Own Spreadsheet is a text-based pairing session where you pair up with me, Christoph, and together we're going to build a spreadsheet application in TypeScript and React using test-driven development.

We're even going to test-drive formulas complete with arithmetic and cell references.

Many introductions to test-driven development use simple examples that work without major hiccups. This book is different. We're going to discuss trade-offs for refactorings and test ourselves "into a corner" where a fix for one test breaks another and deal with everything in the book.

You can find example chapters and try out the spreadsheet built in the book over at: https://buildyourownspreadsheet.com

Thanks,
Christoph
