## Object isFrozen
|
||
|
|
|
||
|
|
You can use <b>`Object.isFrozen()`</b> to figure out if an object is frozen or not. It returns a <b>`true`</b> or <b>`false`</b> boolean value.
|
||
|
|
|
||
|
|
<b><h4>SYNTAX</h4></b>
|
||
|
|
```javascript
|
||
|
|
Object.isFrozen(obj)
|
||
|
|
```
|
||
|
|
<b>For Example:</b>
|
||
|
|
|
||
|
|
```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 <b>cannot</b> have its properties changed.
|
||
|
|
</br></br>
|
||
|
|
If you try to use <b>`Object.isFrozen()`</b> on a non-object argument, it will return `true`.
