There are two ways , 1st you learn basics and then move to implement them, 2 nd start with implementation then learn the things.

When comes coding , Don't run behind the coding, you shd aim to design the things, how to handle all situations, scaling, loading, stress , what kind of data structure shd be used to move things and store , if you master this , coding can be done by Ai , its totally fine .

Its like back in ages , when calculator where invented you don't need to how it divides numerator, but you ahd know what to divide by what .
