Differences between instance properties and prototype properties in JavaScript objects.

09-Oct-2023In JavaScript, objects can have instance properties and prototype properties, and understanding the differences between them is crucial for effective object-oriented programming. These two types of properties serve different purposes and have different characteristics:
Instance Properties:
Prototype Properties:
In summary, instance properties are specific to individual instances of an object, while prototype properties are shared among all instances created from the same constructor or class. Prototype properties are often used for methods or properties that are common to all instances to save memory and promote code efficiency. Understanding when and how to use each type of property is essential for effective JavaScript object-oriented programming.
