These bindings are specified directly in the HTML markup using custom data-bind attributes, making it easy to establish a connection between the UI and the underlying data.
Automatic UI Updates: It automatically updates the UI whenever the underlying data properties change. This two-way data binding ensures that any modifications to the ViewModel are reflected immediately in the associated UI elements, eliminating the need for manual DOM manipulation.
Observable Properties: It provides observables, which are special JavaScript objects that automatically notify subscribers whenever their value changes. Observables can be used to represent individual data properties in the ViewModel, enabling reactive updates to the UI.
Computed Observables: It supports computed observables, which are derived from other observables and update automatically whenever their dependencies change. Computed observables are useful for performing complex calculations or transformations on data and keeping the UI in sync with the computed results.
Dependency Tracking: It automatically tracks dependencies between observables, ensuring that UI updates are triggered only when necessary. This helps to optimize performance by minimizing unnecessary re-renders of the UI.
Template Binding: It includes support for template binding, allowing developers to define reusable UI templates that can be dynamically rendered based on data in the ViewModel. Templates can contain data-bind attributes to establish bindings with the ViewModel properties.
Custom Bindings: It allows developers to create custom bindings to extend its functionality and encapsulate complex UI behaviors. Custom bindings can be used to implement reusable UI components or integrate with third-party libraries.

Redux

Redux is an open-source JavaScript library for managing application state in JavaScript applications, primarily used with frameworks like React or Angular. It follows the principles of Flux architecture and is often used as a predictable state container. Redux is commonly used in large-scale applications where managing state becomes complex and requires a centralized solution.

Features

Single Source of Truth: Redux stores the entire application state in a single JavaScript object called the “store.” This makes it easy to access and manage the state across different components of the application.
Immutable State: Redux state is immutable, meaning that state changes are made by dispatching actions that describe the state transformation instead of directly mutating the state. This ensures that the state changes are predictable and traceable.
Actions: Actions are plain JavaScript objects that represent the intention to change the state. Actions are dispatched to the Redux store and are handled by special functions called reducers.
Reducers: Reducers are pure functions that take the current state and an action as arguments and return the new state based on the action. Reducers specify how the application’s state should change in response to actions.
Store: The Redux store holds the application state and provides methods to retrieve the current state, dispatch actions, and subscribe to state changes. The store is typically created using the createStore() function provided by Redux.
Middleware: Redux middleware provides a third-party extension point between dispatching an action and the moment it reaches the reducer. Middleware can be used for logging, asynchronous actions, routing, and more. Popular middleware includes Redux Thunk, Redux Saga, and Redux Observable.
DevTools: Redux DevTools is a browser extension and development tool that provides debugging capabilities for Redux applications. It allows developers to inspect the state, track actions, and replay actions to debug application behavior.
Selectors: Selectors are functions that compute derived data from the Redux state. They are commonly used to extract specific pieces of state or perform complex transformations on the state before it is used by components.
Integration with React: Redux is commonly used with React to manage the application state in React applications. The react-redux library provides bindings to connect React components to the Redux store and access the state and dispatch actions using React hooks or higher-order components.

Overall, Redux provides a robust and scalable solution for managing application state in JavaScript applications. Its predictable state management and unidirectional data flow make it well-suited for complex applications with dynamic data requirements. However, Redux can introduce additional boilerplate code and complexity, so it is often used in combination with frameworks like React to streamline state management in large-scale applications.

Computed Properties: MobX supports computed properties, which are derived values that are automatically updated when their dependencies change. Computed properties are defined using functions and can be used to perform calculations or derive data from observable state.
Reactions: MobX allows developers to define reactions, which are side effects that are automatically triggered in response to changes in observable state. Reactions can be used to perform asynchronous tasks, update the UI, or trigger other actions based on state changes.
Actions: MobX encourages a structured approach to modifying observable state by using actions. Actions are functions that modify state in a controlled way, ensuring that state changes are tracked and reactions are triggered appropriately.
MobX Tree: MobX State Tree (MST) is an optional extension of MobX that provides a more structured approach to managing complex application state. MST allows developers to define models with properties, actions, views, and relationships, making it easier to manage large-scale state hierarchies.
Integration with Frameworks: MobX can be used with popular JavaScript frameworks such as React, Angular, and Vue.js. Integration libraries such as mobx-react, mobx-angular, and mobx-vue provide bindings to connect MobX state to framework components and manage reactivity.
Performance Optimization: MobX is designed for performance and efficiency, with optimizations such as memoization, batching of state updates, and selective reactivity. This helps to minimize unnecessary re-renders and improve the overall performance of reactive applications.

Overall, MobX provides a flexible and intuitive solution for managing application state in JavaScript applications. Its reactive model, support for computed properties, and integration with popular frameworks make it a powerful tool for building reactive and efficient web applications.
