I've just finished the first part of Dave's challenge. And I was almost there... I'm reay to move on but I just wondered. Why do we not give name for each object in the array literal
var students [
student1 = {
name: "Jonnie",
age: 14,
track: "Web Design",
achievements: 54,
points: 45345
},
student2 = {
name: "Jonnie",
age: 45,
track: "PHP",
achievements: 54,
points: 45345
},
Dave's solution was more like this.
var sudents = [
{
name: "Jonnie",
age: 34,
track: "Front End Track",
achievements: 54,
points: 45345},
},
{
name: "Dave",
age: 25,
track: "Front End Track",
achievements: 54,
points: 45345
}
]
(I surreptitiously added an age key.)
Why is this? I'm pretty sure that if you were creating an object on it's own you'd give it a name. :-) Thanks.

Interesting question! The way I see it, your solution is almost analogous to an associative array or dictionary, while Dave's is a simple array. The use case will define which solution is better.
Best,
Greg

Treehouse Moderator 91,253 PointsThanks Greg, so I guess both solutions would work and I'd maybe do best to follow Dave's model? :_
