"A real programmer does not use the IDE (the Integration development environment), they write code with a text editor with a certain plug-in." "We can always hear such views in some places. However, although more and more people agree with this view, an IDE is still very useful, it is easy to set up and easy to use, so it is no more appropriate to write a project than this. So in view of this, I would like
