Can you run a formatter on your code? https://prettier.io does a pretty good job (hehehe) at it.

The time complexity for removeDuplicates function is O(n²) and space complexity is O(1).
And time complexity for printList is O(n) and space complexity is O(1).

Maybe by using recursion it can be made faster

can you expand on that? usually with recursive algorithms, analysis becomes complicated because of the fact that computation across method calls need to be accounted for.

I'm trying to make it easier to know if your code is correct, so I added support for mocha in #47

Can you change the code so that it follows the pattern found in https://github.com/techqueria/data-structures-and-algorithms/blob/aa70628efaf99a825115cea3c1008a4ef4276816/JavaScript/chapter01/1.1%20-%20Is%20Unique/solution.js ? you might need to change printList() in favor of toString() so that you can use assert.equal(list.toString(), '...');
