  -`ts-jest` configuration is done within Jest configuration object. This latest can be in `package.json` under the `jest` property, or in its own `jest.config.js` file.
  -The later is preferred since it's more customizable, but it depends on your needs and preference.

  ### Basic usage
  -In most cases, simply setting the `preset` key to the desired preset name in your Jest config should be enough to start using TypeScript with Jest (assuming you did add `ts-jest` to your dev. dependencies of course):
