Cons
Con Requires node.js
Slap is written in JavaScript and it requires something to interpret it in a local machine. That something is node.js, but for people who don't need node, it would be a hindrance and an overkill to install node just to use a simple text editor. Furthermore, it can only be used remotely if the remote machine has node installed.
Con CLI only
Slap only runs through the terminal.
