What are the most important elements and concepts, that employers now expect modern web developers to know, in each of the following:
React components, props, and state, as well as familiarity with popular libraries such as Redux, MobX, and React Router.



• React Components: Components are the building blocks of React applications, which allow developers to create self-contained, reusable elements of code that can be easily shared and reused.

React components are written using JavaScript and JSX (JavaScript XML) and are composed of a render function that returns HTML, as well as a set of lifecycle methods that control how the component behaves.

React Components: Components are the building blocks of a React application. They are small, reusable pieces of code that can be composed together to create a larger application. Components are typically written in JavaScript and can accept inputs, known as props, and maintain their own state.



• Props: Props are properties that are passed to a React component when it is created. They can be used to configure the behavior of the component, such as setting its initial state or passing data from an external source. Props are immutable and cannot be changed once they are passed to the component.

Props: Props are data passed from a parent component to a child component. They are used to configure and customize the child component.



• State: State is a JavaScript object that contains data that is used to control the behavior of a React component. It is a dynamic property that can be changed and updated as the user interacts with the application. State is stored locally in the component and can be accessed and manipulated using the setState() method.

State: State is an object that holds data specific to a component. It can be changed by user interactions or data from an API.



• Redux: Redux is a library for managing application state in React applications. It provides a single source of truth for all of the application's data, making it easier to debug and maintain. It also provides a number of tools for managing data, such as reducers and middleware, which allow developers to manipulate and control the application's state.

Redux: Redux is a popular library for managing state in React applications. It provides a predictable way to store and update application state in a single location.



• MobX: MobX is a library for managing application state in React and React Native applications. It provides utilities for working with asynchronous data, such as observables, which allow developers to track data changes and react to them in real time.

MobX: MobX is a library for managing state in React applications. It provides an observable data flow that makes managing state easier and more efficient.



• React Router: React Router is a library for routing and navigation in React applications. It provides tools for creating dynamic routes and links, as well as a router component for displaying the appropriate page or component for a given URL.

React Router: React Router is a library for managing routes in React applications. It provides an intuitive way to handle browser history and link paths with components.

HTML5 Features and APIs: Canvas, Geolocation, Web Storage, Drag and Drop, Video and Audio, SSE, Web Workers, Web Sockets



Web Standards and Accessibility: Web standards are the guidelines for how websites should be designed and developed, and employers now expect modern web developers to be familiar with the various web standards, such as W3C and WAI, as well as the importance of making websites accessible to all users, regardless of their physical or cognitive abilities.
