console.log double posting

+2 Ray LeDuc · March 15, 2015
Hey guys I could use some help. I am just learning about objects within JavaScript and was trying a simple script which runs and gives the expected results with the exception of  it posting twice. I am sure there is a logical explanation as to why but I just don't know why.

var ray = { 
    name: "ray",
    skills: ["JavaScript", "HTML", "CSS" ],
    "favorite color": "blue"

console.log(ray["favorite color"])

so when I refresh the browser it will print the name and favorite color each on a separate line but will do it twice. Any Idea as to why. please help, I am finding my self a bit annoyed by it.

Are you using another piece of software to check your JS code, such as Firebug? That may be the issue. I tried a few versions of the code you supplied above, with some minor changes. You'll note I didn't use the html links in my code, this may be a part of your issue as well.
You'll notice the syntax of my code is slightly different, as I prefer dot notation when available. This is to eliminate possible issues and use proper conventions with the code.

// This section creates an Object called 'ray'
var ray = {
name: "ray",
skills: ["JavaScript", "HTML", "CSS" ],
"favorite color": "blue"
//end object

// begin console logs
console.log(ray["favorite color"];
//end log

The only other thing I can think of, is to check your HTML and see if the <script src="'whatever your JS name is'.js" > is listed twice, causing the procedure to run twice.
Hope this helps, and if it doesn't, please feel free to ask questions!

Hey Doug,

     Thanks for the reply and I use chrome with their dev tools for my js. secondly I didn't put those links their intentionally but needless to say they are there. after applying your code and tried it out I had issues to get it to work however, I found and fixed it and it worked just fine. there was a missing ) but no biggie easy enough to spot and fix. 

Thanks again for your reply and assistance.

and you should  delete the ("") from the property because it's for values like "blue"

favorite color it will look like:
favorite color : ''blue';

@ Ray, 
Yep, I see the Parenthesis I missed, lol thanks. I'm glad you were able to solve the problem. 

@ Sid,
Yes, programming conventions suggest to use a defined attribute rather than a "magic" attribute or dynamically created attribute.
