Provider 'xx' must return a value from $get factory method in AngularJs

I have written an angularjs factory as below

module.factory('LogService', function () {



    function log(msg) {

        console.log(Rahkaran: + new Date() + :: + msg);

    }



    return 

    {

        log: log

    };



});

But I kept getting this error

Provider 'LogService' must return a value from $get factory method

I googled about the error and I couldn't find any solution.

Coincidentally I changed the return statement to this

return{

    log: log

};

And error is gone!!

Is there any differences between having { in front of return or at the next line?

This is called Automatic semicolon insertion

The return statement is affected by automatic semicolon insertion (ASI). There is no line terminator ; between the return keyword and the expression allowed.

return

a + b;



// is transformed by ASI into



return; 

a + b;

So you must insert { in front of return and Not at the next line.
