# Object.clone

## Function

Returns a deep copy of the object.

## Syntax

```bt
object.clone()
```

## Parameters

No parameters.

## Return value

| Type | Description |
| ------ | ------ |
| Object | Returns the new object value. |

## Return object fields

The returned object contains all field names of the original object. Variable containers such as arrays, objects, and class instances will be copied recursively; non-ordinary containers such as functions, regular expressions, dates, and standard library objects maintain the original runtime semantics.

## Example

```bt
user = {profile: {name: 'BT'}}
result = user.clone()
result.profile.name = 'New'

// Output: BT
echo(user.profile.name)
```

## Notes

- clone does not modify the original object.
