How many pages should a web front-end engineer make a day?

Tell me about my experience:

before doing java, I found it boring to write sql and DAO every day, so I turned to the front end.

cut pages, one page a day at first (active page), and learn while writing.

after a few weeks, I am much more familiar with it, and the effect of adding 3~5 active pages a day is not to mention.

I got bored soon, and then I returned to making system forms or something. I did it before and after, and it was not bad to come out one or two times a week, all kinds of verification and data alignment.

After a while, if jQuery slips away, just play something else, and write some basic front-end tools and methods. Usually, it takes two or three days to leave the factory, and the amount of one or two codes is gradually reduced.

Play Nodejs in the back, engage in IO, engage in regularization, and let the program help me write pages, so I write less and less code myself. Now the maximum output is 4 lines a day, and there are many main considerations. Naturally, I have to give more code I write to others to ensure quality and usability.
