What is React?

React is a JavaScript library developed by Facebook which allows you to build UI components. It facilitates the creation of interactive User Interfaces. It also makes the code easier to understand and launch. React Java Script framework uses server-side rendering to provide a flexible, performance-oriented solution.

Angular vs React:

• AngularJS is an open-source platform developed by Google, while ReactJS is
• an open-source library developed by Facebook.
• Angular JS is a TypeScript-based web application framework, whereas
• React JS is a JavaScript-based library.
• While talking about React JS vs Angular, Angular is a JS framework built using
• TypeScript, whereas React JS is a JS library built using JSX.
• React.js is mostly used to build interactive UI components with frequently
• variable data, whereas Angular.js is used to build complex enterprise apps like
• progressive web apps and single-page apps.
• While comparing Angular JS vs React JS, Angular JS is used to build singlepage applications using HTML and TypeScript. React JS is commonly used to
• create user interfaces for single-page applications from isolated components.
• The actual difference between React and Angular is their learning curve –
• Angular is steeper, while React has a moderate learning curve.
• Angular is a part of the MEAN stack and is very compatible with many code
• editors. It’s also considered to develop dynamic websites and web apps. On the
• other hand, React is widely used to develop reusable HTML elements for front
• end development

DOM vs Virtual DOM:

Incremental DOM – when a new DOM is created, it compares it to the previous one and applies the differences to the “actual” DOM, only allocating memory if necessary.

Virtual DOM – anytime the DOM changes, a new virtual DOM is created, compared to the previous one, and only the differences are modified in the “real” DOM.

Oneway Data Binding vs Two way:

Supports both one way and two way data binding ,two-way data binding means that if we modify the UI input, the model state will change, and vice versa.

One-way data binding means that a UI element can’t affect a component’s state.

Library vs Framework:

A library performs specific, well-defined operations.

A framework is a skeleton where the application defines the "meat" of the operation by filling out the skeleton. The skeleton still has code to link up the parts but the most important work is done by the application.
