It can do stuff that running in your browser can not. Since electron runs both the client-side code and the server-side nodeJS you can communicate between the rendering engine and the back-end for tasks that a web browser alone wouldn’t allow you to do, like accessing and navigating your local file system for example. Or if the app has a lot of assets and it needs to work offline, you can have the nodeJS backend download the files and encrypt them and have the front-end query the nodeJS and to get the decrypted assets and use the whole web app offline completely with a local database that you may sync with a webserver at some point later if or when internet connectivity is restored.
For most apps its overkill, but Electron and NodeJS can do pretty much anything a native app can do (just slower and while using a LOT more resources than a native app) but can be done entirely by someone experienced in web frontend development and nodeJS.
If you’ve ever been forced to use Teams you must already know they scraped the bottom of their talent barrel for the team that works on it… The software is shit, riddled with bugs to the point where at one point I used to only be able to use teams on my browser because the desktop app just decided to never let me access the text chat, and the browser version I would load it would be a white screen and I would have to refresh 3 times for it to load. But at least it worked after those 3 refreshes. And it was exactly 3 refreshes every single time, never 2, never 4, and 5 was right out. It was always without fail 3 refreshes. Whether loading from Firefox, Chrome, or Edge. Fortunately we don’t have too many meetings with people using Teams these days, so I haven’t had to use it in a while, but its easily in my top 5 worst software I’ve been forced to deal with. Maybe Top 3. But its still miles behind Magento. Fuck Magento, just thinking of it right now gets my blood pumping and I refused to work with it ever again about 10 years ago… Fuck Magento. Teams is at least a distant 2nd or 3rd to that. Absolute crap.
