Unusual blank space

I tried the following code in my browser and it seems that in the output there is a space in the first line that doesn't appear in the others.

var human = {
    first_name: "Mohammed Khalil",
    last_name: "Ait Brahim",
    age: 18.5,
    bestSongs : ["FireBall", "Uptown Funk", "Bethoven Moonlight Sonata"],
    security: {
        id: 1,
        codeName: "The GyroScope"
    },
    getInfo: function() {
        var s = this.first_name + " " + this.last_name + " : " + this.age + "\n" + "Best Songs : ";
        for(var idx = 0; idx < this.bestSongs.length; idx++)
            s = s + this.bestSongs[idx] + (idx != this.bestSongs.length - 1 ? " - " : "\n");
        s += this.getSec() + "\n";
        return s;
    },
    getSec: function() {
        return "ID: " + this.security.id + "\nCode Name: " + this.security.codeName;
    }

}
console.log(human.getInfo());

Hi Mohammed,

When I run your code in firefox/firebug I see 4 lines of output and they're all aligned on the left.

Could you clarify what you mean and what browser you're testing this in?

This is the output I get:

Mohammed Khalil Ait Brahim : 18.5
Best Songs : FireBall - Uptown Funk - Bethoven Moonlight Sonata
ID: 1
Code Name: The GyroScope

I tested my code on chrome's console.

Here is the result : Imgur

Hi Mohammed,

I did a little searching on this and it looks like this is a problem that has come up with recent releases of chrome. The console is outputting a blank space before the actual output.

Here's a few links you can look over:

http://stackoverflow.com/questions/27569043/extra-space-at-beginning-of-console-log

https://code.google.com/p/chromium/issues/detail?id=444580

According to those links you can either fix the problem now by applying the patch or you can wait a few release cycles and the problem should go away.
