React vs angular comparison which is better

React vs angular comparison which is better, ReactJs is a javaScript library building user interfaces and is developed by Facebook. It is based on JavaScript and JSX, is considered widely for developing reusable HTML elements for front-end development.

Angular is an open-source structural framework for dynamic web applications and mobile apps. It uses HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly. Data binding and dependency injection eliminate much of the code.

Features of React
JSX
JSX is an JavaScript XML. It is a syntax extension of JavaScript. Its an XML or HTML like syntax used by ReactJS.

Components
ReactJS uses components to build an application. ReactJS application is made up of multiple components, and each component has its own logic and controls. These components can be reused in larger-scale projects.

One way Data Binding
ReactJS is designed in such a manner that follows unidirectional data flow or one-way data binding. The benefits of one-way data binding give you better control throughout the application. Flux is a pattern that helps to keep your data unidirectional.

Virtual DOM
A virtual DOM object is a representation of the original DOM object. It works in a one-way data binding approach. When any changes happen in the web application, the entire UI is re-rendered in virtual DOM representation. Then it checks the difference between the previous DOM representation and new DOM. Once it has done, the real DOM will update only the things that have actually changed. This makes the application faster, and there is no wastage of memory.

Simplicity
ReactJS uses the JSX file which makes the application simple and to code as well as understand. We know that ReactJS is a component-based approach that makes the code reusable as your need. This makes it simple to use and learn.

Performance
ReactJS is known to be a great performer. This feature makes it much better than other frameworks out there today. The reason behind this is that it manages a virtual DOM. The DOM is a cross-platform and programming API that deals with HTML, XML or XHTML. The DOM exists entirely in memory. Due to this, when we create a component, we did not write directly to the DOM.

Features of Angular 
CLI Prompts
In angular 7, the command-line interface (CLI) prompts has been modernized to version 7.0.2. With the new and updated version of angular CLI comes new features. When the user executes common commands like ng add @angular/material or ng new, it will prompt users. It helps users to explore the in-built SCSS support, routing, etc. To benefit all packages that publish schematics, CLI prompts have been added to schematics too.

Application Performance
Angular 7 is faster as compared to the previous versions of angular. Certain new features introduced as discussed above make the app run faster and perform better. It does not only focus on making framework small but makes the app small too as much as possible.

Virtual Scrolling
Angular 7 comes with virtual scrolling. Virtual scrolling allows users to bind a list of elements even its too long in small packets. As per the scroll movements, data will be supplied into packets at the user end. This is one of the Angular 7 features, which is beneficial for mobile apps where scrolling can affect performance. But useful for web applications too as even in web applications if we scroll a long list of data, performance gets affected.

Drag and Drop
Now even by dragging and dropping items in the list user can re-order the list. It also allows the transfer of elements between the lists. Using the CDK drag handle, a user can customize the drag area as per requirement. Multiple handles apply on a single item if requires. As per the user’s command, the item may move along the X-axis or the Y-axis because the movement of drag and drop restricts along an axis.

Bundle Budget

While developing applications on Angular 7, now the developers can set up a budget limit of their bundle size. a default setting of the bundled budget has 2 MB as the lower limit and 5 MB as the higher limit. When the initial bundle is more than 2MB, a new application will warn and will error at 5 MB. The developer can also change these settings as per need. Reduction in bundle size improves the performance of the application.

Angular Compiler
The new angular compiler offers an 8-phase rotating ahead-of-time compilation. The NGCC (Angular Compatibility Compiler) will convert node_modules compiled with Angular Compatibility Compiler (NGCC), into node_modules which appear to have been composed with TSC compiler transformer (NTSC). Also, Ivy rendering engine can use such “legacy” package due to this compiler change

Angular Elements
It was introduced in the Angular 6. Since a part of the Angular framework, the angular 7 comes with its new updates. Angular now supports content projection using web standards for custom elements.

Angular Do-Bootstrap
It uses to bootstrap those modules which require bootstrap of components. Angular 7 offers an interface  and new life-cycle hoop

Better Error Handling
Angular 7 improves error handling in an angular application. @Output in angular7.0 has an improved error handling feature.

Native Script
Before Angular 7 developers have to create separate projects for mobile and web versions of the application but Now through a single project, users can build a web and mobile app too. A native script schematics collection provides this functionality. The codes for the web and mobile apps will maintain in such a way that the shareable part keep at one place and non-shareable ones can create separately but in a single project.

Conclusion of React or Angular
React is a small javascript library and whereas angular is an MVC framework and it has a lot of its own functions like animation, HTTP, testing. Angular keeps releasing the version and even react but there will be huge differences in angular versions.
