Minification "compresses" code.

Packing "compresses" and "obfuscates" code.

The most popular packer I believe to be:

However Google Closure one of the highest rated minifiers can also do packing with additional options:

<h3>Obfuscation: Don't do it.</h3>
No matter how hard you try to obfuscate JS, it's easy to de-obfuscate it. There are many plugins available for this purpose. For example, there is <a href="https://addons.mozilla.org/en-US/firefox/addon/10345/" rel="noreferrer">Javascript Deobfuscator</a> for Firefox.
<h3>Do minify though.</h3>
It will save you and your users some bandwidth, improve load times and everybody's happy.

Also, you can run a minifier before using this but do not run this and then use a minifier. Things will likely break.

Hey there is no such thing.

Javascript needs to be interpreted by the browser, and hence has to be readable by the browser... and thus cannot be obfuscated. The ones you find on google are as good as it gets. They can make the javascript slightly hard to read by hand, but on the other hand it's pretty easy to de-obfuscate them.

There is one option if you want to do something to protect your code. You can move your code to the serverside using a server side javascript solution, such as node.js. This will probably make your app overall more complicated but might be worth it if you are really serious about protecting your code.

The meaning of <code>obfuscating</code> is: 
changing the code in a matter that the code will be less readable, but EXACT same functionality and logic!
A very good <a href="http://freejsobfuscator.com/" rel="nofollow noreferrer">free obfuscator</a> that I'm using usually, because it is: 
1] free :) 
2] one way obfuscating! some tools change your functions, by 'eval', which can easily show your ORGINAL code. 
3] add random code inside for harder tracking. 
4] and also, cleans line-breaks + empty spaces.
