Is this an okay format too?

var students = [
  {name:"Bo",track:"ios",achievements: 2, points:3}
  {name:"Moe",track:"web design",achievements:, points:}
  {name:"Jose",track:"java",achievements:2, points:4}
  {name:"Joe",track:"javascript",achievements:3, points:4}
  {name:"Toby",track:"ruby",achievements:4, points:5}
];

it is :) but you have sall mistake your variable is INVALID because you miss "," after taking object to array

also learn use some SPACES after "," and : its more clear for other peoples when you will ask for help because giving random space after "," make feel bad

somewhere you have space and somewhere not its confusing for me =\

Formatting is just style, and ultimately, style is up to you. The spacing here looks weird to me, but if you like it, that's what counts. That being said, if you're working with other people, you'll probably agree on a specific set of style rules, and I'd be willing to bet that this wouldn't be it, so be prepared for that. Like I said before, though, for the purposes of Treehouse code, what counts is that it works and you can understand it

Thanks guys. Appreciate the feedback. Is more of a vertical formatting style a best practice?

I'd say something like this is probably fairly standard, but it depends on the project:

var students = [
    {
        name: "Bo",
        track: "ios",
        achievements: 2,
        points :3
    },
    {
        name: "Moe",
        track: "web design",
        achievements: 3,
        points: 4
    },
    {
        name: "Jose",
        track: "java",
        achievements: 2,
        points: 4
    },
    {
        name: "Joe",
        track: "javascript",
        achievements: 3,
        points: 4
    },
    {
        name: "Toby",
        track: "ruby",
        achievements: 4,
        points: 5
    }
]

Personally, I tend to one-line it. Lots of people don't like it, but that's my style:

var students = [{name: "Bo", track: "ios", achievements: 2, points: 3}, {name: "Moe", track: "web design", achievements: 3, points: 4}, {name: "Jose", track: "java", achievements: 2, points: 4}, {name: "Joe", track: "javascript", achievements: 3, points: 4}, {name: "Toby", track: "ruby", achievements: 4, points: 5}];
