What is dependency injection in JavaScript?
Dependency injection is a design pattern used to implement IoC (Inversion of Control), allowing for better modularity and testing.
Can you give me an example of how to implement it?
Sure! You can use a simple constructor function to inject dependencies. For instance, if you have a service and a controller, you can pass the service as a parameter to the controller's constructor.
What are the benefits of using dependency injection?
The main benefits include improved code maintainability, easier testing, and better separation of concerns.
Are there any libraries that help with dependency injection in JavaScript?
Yes, libraries like InversifyJS and Awilix are popular for implementing dependency injection in JavaScript applications.
