To allow functional components to consume context values in React, you use the useContext() hook. useContext() is a hook provided by React that enables functional components to access the data provided by a Context Provider. It simplifies the process of consuming context values and eliminates the need for a Context Consumer component, making it more convenient for functional components to access context data.

When two components have different types during reconciliation, React unmounts the old child components and replaces them with the new ones. React prioritizes preserving the user interface's integrity and behavior by ensuring that the new component type is rendered correctly. This behavior is crucial for maintaining consistency when components change types.

Overusing React.memo can lead to increased memory usage due to frequent re-renders. React.memo is a memoization function in React used to optimize functional components by preventing unnecessary re-renders. However, if it's applied excessively, it can cause more re-renders than needed, which increases memory usage.

When animating route transitions in a React application, the commonly used component from 'react-router-dom' to manage the different routes is the 'Route' component. The 'Route' component allows you to define which component should be rendered for a specific route, making it essential for navigation and route handling in React applications. The other options are not typically used for managing routes.

To store the previous state or props in functional components, you can use the "useRef" hook. The useRef hook allows you to create mutable references to DOM elements and can be used to store previous values. While the other hooks (useState, useEffect, useMemo) are essential in functional components, they serve different purposes.

React's diffing algorithm updates lists by comparing the old list to the new list element by element. It identifies changes, additions, and removals, allowing for efficient updates without recreating the entire list. This approach is known as "keyed reconciliation" and helps minimize the DOM manipulation required. This is a crucial concept in optimizing React applications.

In React, the common pattern to provide data to many components efficiently, including those using Websockets, is called Redux. Redux is a state management library that allows you to store and manage application state in a centralized store. It facilitates efficient data sharing among components, making it suitable for scenarios where real-time data from Websockets needs to be distributed across many parts of an application.

The primary library for handling immutable data structures in the context of React's performance is "Immutable.js." Immutable data structures help prevent unexpected side effects, making it easier to reason about your application's state. This library can be highly beneficial when used in conjunction with React, improving application performance and maintainability.

React Native is a hybrid mobile app development framework. It allows developers to build mobile applications for multiple platforms (e.g., iOS and Android) using a single codebase in JavaScript and React. While React Native uses native components, it is distinct from native development platforms.

The primary benefit of using TypeScript with React is enhanced code readability and maintainability. TypeScript provides static typing, which helps catch errors at compile time and provides better IntelliSense support. This leads to more robust and maintainable code. While the other options might be desirable in different contexts, they are not the primary benefit of using TypeScript with React.

Immutability in React can lead to more efficient rendering because it reduces the need for virtual DOM diffing. When the state or props of a component are immutable, React can easily compare the previous and current values to determine what parts of the DOM need to be updated. This optimization can significantly improve the performance of React applications by minimizing unnecessary re-renders.

To fetch data from multiple REST endpoints simultaneously and wait for all the data to be available before proceeding, you should use 'Axios.all()' to make multiple requests concurrently. 'Axios.parallel()' and 'Axios.concurrent()' are not standard Axios methods, and 'Axios.series()' would make requests sequentially, not concurrently.
