Dev Dependencies

ts-jest

A Jest transformer with source map support that lets you use Jest to test projects written in TypeScript.

It supports all features of TypeScript including type-checking. Read more about Babel7 + preset-typescript vs TypeScript (and ts-jest).

We are not doing semantic versioning and `23.10` is a re-write, run `npm i -D ts-jest@"<23.10.0"` to go back to the previous version
