How to implement Obfuscated javascript code [duplicate]

Question

Help me out!

I would like to ask how to implement my Obfuscated code?

heres my sample code

var accessToken = $('#access_token').val();
var myapp = angular.module("loginApp", []);


myapp.controller("loginCtrl", function ($scope, $http) {
    $scope.log_username = '';
    $scope.log_password = '';
    $scope.loginfirst = $("#reqerr").val();

sample code obfuscated code

eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c])}}return p}('3 4=$(\'#8\').2();3 1=7.6("5",[]);1.g("9",e($0,$f){$0.d=\'\';$0.c=\'\';$0.a=$("#b").2();',17,17,'scope|myapp|val|var|accessToken|loginApp|module|angular|access_token|loginCtrl|loginfirst|reqerr|log_password|log_username|function|http|controller'.split('|'),0,{}))

my problem is how do i implement it? i tried to replace my sample code with obfuscated code, i got an error, and i have no idea on how should i implement it?

PS dont mind the code above , its just a sample..

What error do you get? And, above all, what do you mean with "implement my obfuscated code"? — MaxArt

"Don't". Obfuscated code is just hard to work with an inefficient. — Quentin

you need add () brackets around function declaration, now you have function(...){...}(...) but you need (function(...){...})(...) — Grundy

You need a special tool like google's closure compiler, but before that you need to properly inline annotate your services like so...

myapp.controller("loginCtrl", ["$scope", "$http", function ($scope, $http) {
    ....
}])

This statement clarifies why, and is correct.

"When minifying, variable names are changed to save space. That means the $scope variable could be renamed to 'a', which interferes with AngularJS' dependency injection. Annotating the services allows AngularJS to keep the relationship between minified variables and the service they represent" - bob esponja

Then follow the steps below:

Step 1) Download http://dl.google.com/closure-compiler/compiler-latest.zip

Step 2) run (you need to install java's JRE or JDK)

java -jar compiler.jar --js hello.js --js_output_file hello-compiled.js
