Hello! So you are new using this console!, Lets get you started
Node.js
npm i javascriptconsole -g
Its very simple to use! When you execute it using 'js'(node.js required) it asks you for a code for it to be executed, after you write it, press enter, the result of that code will be logged into the console.
Plugins are additions to the console, they are javascript files that have functions, When you execute the 'help' command you will see all the plugins you have installed and its IDs. For Execute a plugin function use 'plug[ID].func.(Function)'.
Developing plugins is not that hard, if you know how to make libarys, you will know how to make plugins. Its easy, just create your own functions and then export them using 'module.exports'
function sum(x,y){
return x+y
}
module.exports = {sum}
