Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
Dependency injection helps in achieving loose coupling between classes.
It allows for easier testing by mocking dependencies.
There are three types of dependency injection: constructor injection, setter injection, and interface injection.

Optimizing a React application involves code splitting, lazy loading, minimizing bundle size, using memoization, and optimizing render performance.
Implement code splitting to load only necessary code for each route or component.
Utilize lazy loading to defer loading of non-essential components until they are needed.
Minimize bundle size by removing unused code, optimizing images, and using tree shaking.
Use memoization te...
