The virtual DOM improves performance by minimizing the number of updates needed to the actual DOM.
Virtual DOM allows for efficient batch updates to the actual DOM, reducing the number of reflows and repaints.
It compares the virtual DOM with the actual DOM and only updates the necessary changes, instead of re-rendering the entire DOM tree.
This results in faster rendering and better performance, especially for complex UI

Generators in Python are functions that allow you to iterate over a sequence of items without storing them all in memory at once.
Generators are created using a function with 'yield' instead of 'return'.

Encapsulation restricts access to certain components within a class, protecting the data.
Abstraction hides complex implementation details and only shows the necessary features.
Polymorphism allows objects to be treated as instances of their parent class.
