Prepare for your Javascript interview
Prepare for your Javascript interview with the most asked question about Prototype Proto. Learn all about how Javascript handles prototypes and proto with this informative video!
*Proto vs. Prototype*
In JavaScript, these terms are closely related to object-oriented concepts like inheritance and the prototype chain. However, they have distinct meanings:
- *Prototype:*
- A special object that serves as a blueprint for instances created using a constructor function.
- Holds shared properties and methods that objects inherit.
- Accessed using the constructor's `.prototype` property.
- *Proto (or __proto__)*
- An internal property within an object that references its prototype object in the prototype chain.
- Provides a way to access the inherited properties and methods from the prototype.
- Accessed using the object's `__proto__` property (not recommended for modification due to potential issues).
*Key Points:*
- Prototypes are used for defining reusable properties and methods.
- Objects inherit from their prototypes through the prototype chain.
- You can modify the prototype to add or change properties/methods that will be reflected in all instances created from that constructor.
- While `__proto__` is technically accessible, it's generally recommended to use other mechanisms like setting properties directly on the prototype object for better maintainability.
By understanding these concepts, you can effectively leverage inheritance and code reuse in your JavaScript applications.
