string http response != same string in javascript

Question

I'm building a web app that uses Angularjs. In one of my controllers I make a call to the backend that returns the current login status of the user.

   $http.get('http://localhost:3000/status')
     .success(function(status) {
       if (status == 'internal') {
         // do stuff...

Even when the requests responds with status equal to 'internal', (status == 'internal') evaluates to false. To test this a bit I put

  $http.get('http://localhost:3000/status')
    .success(function(status) {
      console.log(typeof status)
      console.log(status)
      console.log(status == "internal")

which prints

    string 
    "internal" 
    false

Any Ideas about what could be going wring here?

what happens when you use 3 equality marks? (status === 'internal') also, can there maybe be some extra whitespace or something like that? — yuvi

make sure no extra white space being sent...check length of status vs length of your test string — charlietfl

Are you returning internal or "internal" (with quotes). I ask because console.log(typeof status) would display as a string but you didn't double quote that in your output. — John Strickler

Sorry, this is only a valid answer if you're using Chrome. It looks like Firefox will wrap strings in quotes on the console.

Your string has extra quotes around it. console.log(string) won't show quotes. Observe:

console.log("what")
what

The only way you're seeing "internal" instead of internal is if you have extra quotes around your string.

This should be what you're looking for:

console.log(status == '"internal"');
