please explain the difference in the out comes of this array versus hash? var a=['hi','buddy']; var b ={hi: 'buddy'};

Question

In my studies in javascript thus far, which have been limited.  Ive heard learned a bit about arrays,  but I haven't come across any explanation of a hash yet. This is a question Im being asked so I'm just curious if anyone could explain it to me.  And maybe post what the outcome would look like and why.  thanks anyone

Arrays are bound to only storing data types. example
```javascript
var car = ["Fiat", 500, "850kg", "white"];
//accessing information
console.log(car[0]); // Fiat
console.log(car[1]); // 500
console.log(car[2]); // 850kg
console.log(car[3]); // white
```
as you can see, there's not much information as to knowing exactly what the data means but with object literals you can organize your data and easily access that information using dot notation. example
```javascript
var car = {
  make: "Fiat",
  model: 500,
  weight: "850kg",
  color: "white"
};
//accessing information
console.log(car.make); // Fiat
console.log(car.model); // 500
console.log(car.weight); // 850kg
console.log(car.color); // white
```
In addition to using object literals is that you can also create and call functions as well.
I hope this helps.
