The delete operator deletes both the value of the property and the property itself. After deletion, the property cannot be used before it is added back again. The delete operator is designed to be used on object properties. It has no effect on variables or functions. The **delete** operator deletes a property from an object.
```

### Answer by Muskan Digital
In JavaScript, you can remove a property from an object using the **delete** operator. Here's how you can do it:
```plaintext
var obj = { property1: "value1", property2: "value2", }; // Remove a property delete obj.property1; // Check if the property is removed console.log(obj.property1); // Output: undefined
```
In the above example, we have an object `obj` with two properties `property1` and `property2.` To remove `property1`, we use the `delete` operator followed by the object name and the property name `(delete obj.property1)`.
After removing the property, if you try to access it, it will return `undefined`, as demonstrated by `console.log(obj.property1)`.
Note that the `delete` the operator removes the property from the object directly. If the property is inherited from a prototype chain, it will not affect the original prototype object.
