I will only post a metaphor

Let's take a look at how a bricklayer works:

Craftsman 1: first draw a horizontal line, when building each brick, are compared with this horizontal line, so that each brick remains horizontal.

Craftsman 2: Build a row of bricks and draw a horizontal line to see which bricks have problems and then adjust them.

What kind of work method do you choose? You will be jealous of the craftsman! This is a waste of time! However, if you want to writeProgramHow is it done? We work in the way of craftsman 2! Sometimes it is even dumb than craftsman 2, because the whole wall is finished and "Integrated Test" is carried out directly, so the whole wall is often collapsed. Do you still think your method is brilliant?
