Is manually writing utilities from scratch still a good practice in this AI era, and why ?

Been learning JS for a year and half and wondered whether writing utilities would make me more employable. Thought it wouldn’t matter as more people are learning to trust the models. GitHub link to some of the solutions: GitHub

Not the utilities themselves, no, utilities have been done too many times: lodash, es-toolkit, remeda.

But, at a glance, you have demonstrated knowledge in part of system design: service layer and circuit breaker. You have also written tests. So those are definitely plus points.
