A higher-order component (HOC) is an advanced technique for reusing component logic. Concretely, a higher-order component is a function that takes a component and returns a new component.

Angular HOC

Below is sample HOC withTheme and obviously the code received the component, insert the theme data and return decorated component. Annotated or attached the HOC to the class component is called meta-programming using typescript decorator.

Meta-programming is a technique by which you can modify the code dynamically at runtime.
