Triple equals type checking?

Where `item.equippable` is a boolean, 

```
if (item.equippable == 24) {
  return new Equipment(item);
} else {
  return null;
}
```

Doesn't type check, but this does:

```
if (item.equippable === 24) {
  return new Equipment(item);
} else {
  return null;
}
```

Is there just not type checking support on triple equals?
