If you'd like to learn how to code Bukkit plug-ins, these guys have quite a few tutorials on it: https://www.youtube.com/user/TheBCBroz/videos

Here.
Basics:
[code]
libraries = [
//default library title would be "script_name",
"reloadPlugins",
"joinScript",
"chatFilter"
];
var debug_messages = true;

function log(msg, level, verbose) {
if (verbose && !debug_messages) return;
if (!level) level = "f";
if (msg instanceof Array) {
for (var i in msg) {
loader.server.consoleSender.sendMessage("\xA7" + level + "[PlugJS] " + msg[i]);
}
} else {
loader.server.consoleSender.sendMessage("\xA7" + level + "[PlugJS] " + msg);
}
}
var block = {
};
var enchantment = {
};
var entity = {
};
var inventory = {
};
var painting = {
};
var player = {
};
var server = {
};
var vehicle = {
};
var weather = {
};
var world = {
};
var js = {
};
var spout = {
screen: {},
slot: {},
key: {}
};
var exports = {
};

var iced;
var CoffeeScript;
function loadLib(lib) {
log("Loading core script " + lib, '2', 'verbose');
load("./plugins/PlugJS/core/" + lib);
}

loadLib("node-path.js");
loadLib("lang_helpers.js");
loadLib("stopwatch.js");
loadLib("js_persistence.js");
loadLib("core.js");
loadLib("compile.js");
loadLib("async.js");
loadLib("tt_war_helpers.js");
loadLib("coffee-script.js");
loadLib("iced.js");
loadLib("icedlib.js");
loadLib("econ.js");
loadLib("metadata.js");
getPlugin("PlugJS").js.eval(read_file("./plugins/PlugJS/core/linq.js"))

iced = exports.iced;

for (var i in libraries) {
require(libraries[i], "libs");
}

log("Finised loading scripts", '2');
[/code]
My loader:
[code]
// Generated by CoffeeScript 1.6.3
(function() {
String.prop('reloadPlugin', {
get: function() {
return function() {
Bukkit.server.pluginManager.disablePlugin(this.plugin);
return Bukkit.server.pluginManager.disablePlugin(this.plugin);
};
}
});

}).call(this);

[/code]

Go to Khan academy, you can learn quite a few different types of programming languages, currently I'm learning Java. It is provided in a fun and interactive way. I've spent about 5 hours in the past 2 days just learning how to code in school! I really can't put it down and wouldn't want to spend my time any other way.

The New Boston on youtube.

would u reconmmend telling me how to?

Just don't get confused between Java and JavaScript - they're not the same. Minecraft uses Java, so perhaps you want to learn that instead of JavaScript?

Butterbacon16 do you know how to program a plugin?

I have been looking for something like this too, but it would help what kind of programming you want to learn (like you want to make a plugin, or just full on java scrip game makeing ext.)?
