I'm not talking about 'unfettered'. It would be great for me to -natively- let users write-to/modify text-only files in the same folder as the parent file. I fail to understand why this has to be hard, dangerous (it'd certainly be useful ... to them AND to me). Real languages have a WRITE command.
FileReader was a big step forward that took forever to arrive. Where's FileWriter?
Thanks for that, but I'm talking about user-initiated writing to separate, editable, plaintext, named files in the same local folder as the parent HTML/JS source. NO web interaction needed or desired, no other knowledge of or access to filesystem desired. For example, browser as IDE. Or database editor/searcher. Powered by JS.
The only way you'll get that is to use something like electron that gives you access to node resources. The browser is sandboxed for a reason, and what you're talking about would be a violation of that. The good thing is Electron apps are incredibly portable.
