Is it recommended to know how to create an array (data structures in general) from scratch?

I noticed while reading through this page that the approach for using an array native to the language is explained, but the topic of creating an array from scratch is not explored.

Is it recommended to take time to learn how to implement every data structure from scratch? Or should we spend more time on learning the strategies for solving the associated algorithm problems instead?

I'm just wondering what the better use of time for prepping for coding interviews would be. Thanks!
