## Object isFrozen
You can use `Object.isFrozen()` to figure out if an object is frozen or not. It returns a `true` or `false` boolean value.
SYNTAX
```javascript
Object.isFrozen(obj)
```
For Example:
```javascript
var foods = {
grain : "wheat",
dairy : "milk",
vegetable : "carrot",
fruit : "grape"
};
var frozenFoods = Object.freeze(foods);
var areMyFoodsFrozen = Object.isFrozen(frozenFoods);
\\ returns true
```
Remember, a frozen object cannot have its properties changed.
If you try to use `Object.isFrozen()` on a non-object argument, it will return `true`.
