Hej folks,

while I wanted to work on this library for a proposed fix, I realized that the current linter setup was not actually linting TypeScript files. (I've screwed up this globbing vs. --ext a couple times myself 😅 )

To make it easier to track the changes I've split up the work into multiple easy-to-review commits, and would recommend to not review chore: ESLint autofixes (0a5d8bd) as it exclusively enforces linting rules you've set up previously and they are tested by the ESLint autofix implementation.

The two biggest changes are replacing a single forEach with a for-of loop to fix no-unused-expressions and introducing a new innerComplexities variables to fix no-param-reassign.
