AngularJS Vs ReactJS

ReactJS

For creating user interfaces, React is a declarative, effective, and flexible JavaScript library. It is the “V” in MVC. ReactJS is a free, component-based front-end library that is exclusively in charge of the application’s view layer. Facebook looks after it. The declarative approach used by React, which seeks to be both effective and versatile, makes it simpler to reason about your application. For each state in your application, it creates straightforward views, and React will quickly update and present the ideal component whenever your data changes. Your code becomes more dependable and troubleshootable when using the declarative view.

React js features include:

  • Scalability: Due to its customizable structure and scalability, it is appropriate for large-scale applications.
  • Rich JavaScript Library: To add much more functionality, developers from all around the world are working hard.
  • Code reuse: This feature enables developers to use previously written code from various levels again when working on a project.

This sample shows the straightforward syntax of React.js.

import React from 'react';
import ReactDOM from 'react-dom';

var name = "Learner";
var element = <h1>Hello, { name }.Welcome to Learn Code Zone.</h1>;
	
ReactDOM.render(
	element,
	document.getElementById("root")
);

AngluarJS

Google developed the well-known open-source Angular framework for building web applications. Frameworks like Angular or React are used by front-end developers to present and manipulate data effectively. In particular, the main logic was transferred to various modules, making updated Angular far more efficient than the prior version. Because of this, it has become considerably faster and smoother than the older one. brand-new angular CLI. You can build a scaffolding for your Angular project using that package.

Angular’s attributes are:

  • Accessibility: Because it has ARIA-enabled components, it makes access easier.
  • Templates: Angular has a number of templates that may be used to quickly generate user interface views by supplying and proposing certain syntax.
  • Testing is made simpler by the program’s division into multiple sections. In this instance, testing is done through the protractor.

This example shows a straightforward Angular programme.

app.component.html:

<hello name="{{ name }}"></hello>
<h2>
  Weclome to Learn Code Zone
</h2>

app.component.ts:

import { Component } from '@angular/core';
 
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'LearnCodeZone';
}

app.module.ts:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
 
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';
 
@NgModule({
  imports:      [ BrowserModule, FormsModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }
