It’s all about cross platform support. The reason you will see advantages listed this way is because the web browser is the real competitor here. So when people talk about what Electron can do they are comparing to the most obvious alternative of a web app.
You’re also competing with native mobile tool sets on native.
If you want to write software for a platform, write software for that platform. Don’t write software for some other platform, try to make it fit, and then declare it good.
People using desktop toolsets never even have to think about that "problem" because it just doesn't exist when you're using the right tools.
There are three types of tools for every job..
* The right kind
* The wrong kind
* The wrong kind but we'll make it work
Electron hits squarely in the third category by hiding the browser and webserver and pretending it's a real desktop application.
