Failing tests when importing and using "select" or "modulo"

[AnderssonChristian]

Describe the bug
The following error is thrown when running unit tests with Jest:

SyntaxError: Unexpected token 'export'

> 1 | import {Coord, CoordArray, select, modulo} from 'media-overlay-library';

To Reproduce
Import and use either select or modulo from the library.
For some reason this seems to only happen when running my unit tests with Jest. I get no errors on build with webpack.

Environment (please complete the following information):

• OS: Ubuntu 20.04.3 LTS
• Yarn v3.0.2 with node v14.9.0
• Media-overlay-library version: 4.1.2
