What types of built-in objects are there?

Built-in object types include data type objects, time and date objects, mathematical calculation objects, error handling objects, file and file system objects, network and communication objects, browser environment objects, other special-purpose objects, etc. Detailed introduction: 1. Data type objects include Number, String, Boolean, Array, and Object; 2. Time and date objects include Date and Time; 3. Mathematical calculation objects include Math; 4. Error handling objects include Error; 5. Files and File system objects and so on.

Types of built-in objects can be classified according to their purpose and functionality. The following are some common built-in object types:

1. Data type objects:

Number: Numeric type object.

String: String type object.

Boolean: Boolean type object.

Array: array type object.

Object: Object type object.

2. Time and date objects:

Date: Date type object.

Time: time type object.

3. Mathematical calculation objects:

Math: Mathematical calculation related objects.

4. Error handling object:

Error: Error type object.

5. Files and file system objects:

File: File type object.

FileSystem: File system type object.

6. Network and communication objects:

These are just some common examples of built-in object types. The specific built-in object types will also vary depending on the programming language and development platform used. Different programming languages ​​and development platforms may provide different built-in object types to meet different needs and functions.
