Memo() is a HOC in React, whereas useMemo() is a React Hook. If the dependencies to a function have not changed, we can use useMemo() to return memoized values and avoid re-rendering.
useMemo() hook. useMemo() is a built-in React hook that accepts 2 arguments — a function compute that computes a result and the dependencies array

useMemo() vs useCallback()
Memorization should be used with caution.
Final Thoughts
With 15 hooks, you may accomplish functionality similar to that of a class-based component. The React team has given all hooks. The most frequent hook is useState, however different hooks may be used depending on the needs of the programme.
If you're familiar with the React class lifecycle methods, the useEffect Hook can be thought of as a beginner's version of componentDidMount, componentDidUpdate, componentWillUnmount, and getDerivedStateFromProps. It's easier to write the logic in one place.
Hooks improve React by allowing you to write simpler code that accomplishes identical functionality more quickly and effectively. Without developing classes, you can implement React state and lifecycle methods. The code examples below show how to use React class and functional components.
