I wouldn't say practice, but simply experience, at least in conventional development, learning patterns goes a long way but learning when to use them correctly is something you can only gain with experience.

learning the minor quirks of languages that they all have comes only with experience.

like Vue for example a competent dev can go through the docs one day and start doing stuff with it the next day in my opinion, but doing really well with it comea down to familiarity with similar stuff like react/angular if you don't have that it will take some time to code vue well.

all that being said some people are just more technical than others imo and communicating in "computer language" simply works better for some than others.
