* Hello, dear curious visitor. I am not a web-guy, so please don't judge my horrible JS code.
|
|
* In fact, please do tell me about all the things I did wrong and that I could improve. I've been trying
|
|
* to read up on modern JS, but it's just a little much.
|
|
*
|
|
* Feel free to open tickets at https://github.com/binwiederhier/ntfy/issues. Thank you!
