What are the Differences between Angular and React

 Framework Vs. Library

Angular is a complete framework while React is a JavaScript Library. Angular uses a two-directional data flow process where it updates the Real DOM directly while React updates only the Virtual DOM and is concerned with the one-directional data flow. While React can be bundled with other programming libraries, Angular is a complete solution in itself. For uni-directional data flow, React needs to be augmented by Redux.

The Major Differences Between React and Angular

Data Binding

Angular allows two-way data binding while React allows one-way data binding.

Two-way data binding means that any changes you make to the model affect the view, and vice versa.

One-way data binding means any changes you make to the model affect the view, but not the other way around. This way, the data only flows in one direction.

These are also called Bidirectional and Unidirectional data flows, respectively.

DOM Usage

DOM is the Data Object Model of a web app. You can either use a regular DOM or create a virtual DOM.

Angular uses the browser's DOM, while React uses a virtual DOM.

A virtual DOM is a simplified version of the DOM. By using a virtual DOM, you can change any element very quickly and without needing to render the whole DOM. It drastically changes the performance from good to excellent.

Imagine the difference in performance in needing to render all 100 items when just a single item is changed, then just rendering a single changed item and not rendering the rest.

Using the virtual DOM is quite the buzz nowadays because it is faster, and speed is key!

Language

Angularis a JS framework by nature, but is built to use TypeScript. React, on the other hand, is a JavaScript library as well, but recommends using JSX.

The difference lies here: TypeScript is a superset of JavaScript while JSX is Javascript but with extended XML syntax.

If you want the best of Angular or React, you must learn to use TypeScript or JSX, which brings me to my next point.

The creators of JSX claim it's faster, safer, and easier than JS
