Reimplementing existing libraries

Hi guys,

Do you guys reimplement libraries from A to Z just to be a better programmer, e. G. Implementing again underscore.js?
What is it worth in terms of finding a job compared to do more concrete stuffs like building a game or javascript30. Does it have value?
How do you put such a project vs building a game for example in terms of difficulty?

Thank you for your answers. :slight_smile:


If you want a better understanding of how libraries that you use work, contribute to them.

Ok, thank you for your answer.
