ObjectId.valueOf()

ObjectId.valueOf()

Returns:The value of the ObjectId() object as a lowercase hexadecimal string. This value is the str attribute of the ObjectId() object.

Changed in version 2.2: In previous versions ObjectId.valueOf() returns the ObjectId() object.

In the following example, call the valueOf() method on an ObjectId (e.g. ObjectId("507c7f79bcf86cd7994f6c0e")):

copy

ObjectId("507c7f79bcf86cd7994f6c0e").valueOf()

This will return the following string:

copy

507c7f79bcf86cd7994f6c0e

You can confirm the type of this object using the following operation:

copy

typeof ObjectId("507c7f79bcf86cd7994f6c0e").valueOf()
