Notepad is definitionally not an IDE. It is not an integrated environment -- and anyone who is intentionally using it over alternatives is almost certainly doing so precisely because they do not want their text editor to be an integrated environment.

I'm sure there's some case where Notepad is PART of an integrated environment, but it would have to be with support of other tools -- likely a terminal of some sort.

The reason other text editors like -- like Notepad++ or Neovim -- can be full IDEs is because they have plugins to generate that integrated experience.

Notepad is used by anyone who wants to see what is actually in a text file.

It's used a lot for stuff where data is transferred in a text format. Comma separated files etc. are still widely used for transferring data flawlessly without having to convert types or mapping a document standard or whatever method that could potentially fuck up or just take more time. It's simple and it works.

F.i if you open a file in excel or word, change one character and then save, you can bet that the entire file is fucked up afterwards, because those programs don't show the data directly. The moment you open it, it might very well be fucked up just from that. If you transfer a file by some kind of JSON format, which is all the rage currently you'll have to map it from both ends, and it also begs the question: Why are we doing running all this code just to transfer one byte?

The beauty of text files is that it's (almost) raw data. (Only "almost" because there are still different localization standards that can fuck up even a text file.)

Notepad covers that. Of course we could use other apps for viewing data, but most of the time, it actually is text and not hexidemal codes or whatever you can save in bytes.

Programming wise, the only thing I use notepad for is making DOS batch files. Again, because it's raw text and should be created and read as such. No parsing, no compiling. Just text. I'll also use it for storing data for programs, because it's easy and raw.

For actual programs, it'd be better to get Notepad++ or MS visual studio code, which at least will highlight commands and collapse functions etc. And still, these also aren't actually IDEs, because they don't compile the code (unless you get those add-ins).

We could also use those for text files as well, but it's overkill. I don't really want to open an app to view data. Notepad is small and quick and not bloated with features, which is ideal for whenever I only want to see what's in the file.

The original MS Paint was similar for pictures. They fucked that up real good. Its been..14 years and I haven't really gotten over how bad it is. It used to be pixel perfect and logical, but now you can't even save a file with transparency, but hey here's s brush with stroke width and blur that'll make sure you can't edit a single pixel. Way to go Microsoft.

If they do the same to Notepad, I'll have to resign my job, because it's not going to work like that.

Notepad++ may very well be widely used as an IDE. Notepad isn't. Other than the name they have nothing do do with each other. It's just a plain text editor with absolutely no features. Maybe some people use it to write code but unless you can't use anything else, even a web browser,, why would you.
