You're not quite taking into account the behavior of `this` in JS. `this`
is set at call-time, so when you do
```
class items {
// ...
getItem3(){
return this.$3;
}
}
```
`this` depends on how `getItem3` was called. In your case if you do
```
myItems = new items();
myItems.getItem3();
```
`this` will be `myItems` because that is how you have called it, meaning
that `getItems3()` will behave just like if you had done `myItems.$3`.
Your code works as expected in this Fiddle: https://jsfiddle.net/2dgefd9d/
