In JavaScript, predefined objects are built-in objects that are provided by the language to facilitate common programming tasks. Examples include Math, which provides mathematical constants and functions; Date, which allows for date and time manipulation; and JSON, which enables parsing and stringifying JSON data. These objects come with various methods and properties that help developers perform operations without needing to define them from scratch. They are part of the standard JavaScript environment, making them readily available for use in any JavaScript code.

Yes, in JavaScript, objects can be thought of as similar to everyday objects because they both contain properties and behaviors.

This analogy helps in understanding how data is organized and manipulated in programming.
