React.memo

With React.Memo, we can make the functional component to behave like a class pure-component.

We create new constant that'd keeps the result of React.memo function:

import { memo } from "react";

const SomeComponent = memo(function SomeComponent(props) {
  // ...
});

[!danger] Mind the Pure Component

React.memo effectively makes the fn component the Pure Component, with all its advantages and drawbacks.
