CodeCademy Intro to Objects II Trouble finding error

For this assignment the object 'languages' was created for you. the assignment is to use a 'for-in' loop to write three different ways to say 'hello.' I want to use an 'if' statement to check that the property is a 'string' and if so, print that version of 'hello' to the console. I am stuck and getting an error stating a "there was a problem with your syntax." 

var languages = {
    english: "Hello!",
    french: "Bonjour!",
    notALanguage: 4,
    spanish: "Hola!"
};

// print hello in the 3 different languages
for (var x in obj) {
    var typeCheck = languages.x;
    if {
        (typeof typeCheck === "string") {
            console.log(typeCheck;)
        }
    }
}

Using the code suggested by Robin, I've modified it to be the following final solution.

for (var x in languages) { 
    var typeCheck = languages[x]; 
    if (typeof typeCheck === "string") { 
        console.log(typeCheck); 
    }
}

You are looping with an undefined variable obj. Use the defined one languages instead.

for (var x in languages) {
    var typeCheck = x;
    if {
        (typeof typeCheck === "string") {
            console.log(typeCheck;)
        }
    }
}

Update

I noticed there was a lot errors in your code.

Your if statement

Which is not how to use it, currently it is :

if {
      (typeof typeCheck === "string") {
        console.log(typeCheck;)
      }
}

Change that to :

if (typeof typeCheck === "string") {
     console.log(typeCheck);
}

Then your ending semi colon on the console.log(), it should be after the ending ).

So from :

console.log(typeCheck;)

To :

console.log(typeCheck);

Putting them together :

for (var x in languages) {
    var typeCheck = x;
    if (typeof typeCheck === "string") {
            console.log(typeCheck);
    }

}

There's a few problems here:

  • for (var x in obj) { - This loops on some object obj which is undefined in this context. You need to loop over languages.
  • if { - if statements have the form form of if (condition), not what you have there.

Here is a correctly version that loops over the enumerable properties of languages and performs the type check. 

    var languages = {
      english: "Hello!",
      french: "Bonjour!",
      notALanguage: 4,
      spanish: "Hola!"
    };

    Object.keys(languages).forEach(function(key) {
      if (typeof languages[key] === "string") {
        console.log(languages[key]);
      }
    });
