newObj

newObj is not a built-in construct. In programming tutorials and sample code, newObj is a conventional variable name used to refer to a freshly created object instance. It serves as a neutral placeholder to illustrate object creation, property assignment, or data storage.

In JavaScript, for example, a newObj might be created as an empty object literal, var newObj = {}; or by calling a constructor like newObj = new Object(); It may then be populated with properties, such as newObj.name = 'Alice' and newObj.age = 30. In object-oriented languages such as Python or Java, the analogous operation is creating an instance of a class (for Python, newObj = MyClass()) or new MyClass() in Java.

As a concept, newObj represents a distinct data container with its own state. It can be used to group related data (key-value pairs) or to encapsulate behavior when defined as an instance of a class. Variants include factory functions that return a new object, or shallow and deep copies of existing objects assigned to newObj.

Naming conventions vary; more descriptive identifiers are often preferred in production code to improve clarity. When documenting code, it is common to explain that newObj refers to a recently constructed object, and to describe its properties and methods.
