FAQs on Node js tutorial step by step 10 Object Factory Video Lecture - The Complete NodeJS Developer Course (in Hindi) - Back-End Programming
| 1. What is an object factory in Node.js? |  |
Ans. An object factory in Node.js is a design pattern that allows the creation of objects based on a predefined blueprint or template. It provides a way to create objects dynamically, with different properties and behaviors, without the need to explicitly define each object individually.
| 2. How does an object factory work in Node.js? | |
Ans. In Node.js, an object factory works by defining a factory function that encapsulates the logic for creating objects. This function accepts parameters to customize the object's properties and behaviors and returns a new object based on the provided parameters. This allows for the creation of multiple objects with different configurations using the same factory function.
| 3. What are the advantages of using an object factory in Node.js? | |
Ans. Using an object factory in Node.js offers several advantages. First, it promotes code reusability by providing a centralized place to create objects with different configurations. Second, it helps in managing complex object creation logic, making the code more modular and maintainable. Third, it allows for easy customization of object properties and behaviors without modifying the factory function. Lastly, it provides a clear separation between object creation and object usage, enhancing code readability.
| 4. Can an object factory in Node.js be used for dependency injection? | |
Ans. Yes, an object factory in Node.js can be used for dependency injection. By defining a factory function that creates objects with injected dependencies, you can easily manage and control the dependencies of your objects. This helps in keeping the codebase loosely coupled and facilitates easier testing and swapping of dependencies.
| 5. How can I implement an object factory in Node.js? | |
Ans. To implement an object factory in Node.js, you can define a factory function that takes parameters representing the desired object configuration. Inside the function, you can create a new object and set its properties based on the provided parameters. Finally, you can return the created object. This allows you to create multiple objects with different configurations using the same factory function.
