Angular is a frontend framework created by Google for building single-page applications. It uses TypeScript and allows developers to write HTML and TypeScript code. Angular is commonly used in the MEAN stack with MongoDB, Express.js, Angular, and Node.js. The document then provides details on key Angular concepts like the DOM, TypeScript, data binding, and testing. It recommends Angular for development teams with backend experience or for complex but less interactive applications.

3.  Google created Angular after the failure of Angular JS.
 Angular is a platform and framework for building single page
client applications using HTML and Type Script.
 Angular is used as the frontend of the MEAN stack, consisting of
Mongo DB database, Express.js web application server
framework, Angular itself (or Angular JS) and Node.js server
runtime environment.

4.  Document Object Model
DOM (Document Object Model) treats an XML or HTML document
as a tree structure in which each node represents a part of the document.
 Type Script
Type Script defines a set of types to JavaScript, which helps users
write JavaScript code that is easier to understand. All of the Type Script code
compiles with JavaScript and can run smoothly on any platform.
 Data Binding
Data binding is a process that enables users to manipulate web page
elements through a web browser. It employs dynamic HTML and does not require
complex scripting or programming .
 Testing
Angular uses the Jasmine testing framework. The Jasmine framework
provides multiple functionalities to write different kinds of test cases. Karma is the
task-runner for the tests that uses a configuration file to set the start-up, reporters,
and testing framework.

5.  If you have a development team is having proper
backend experience
 If you’re developing a complex but less interactive
application
 If an enterprise is planning to a particular framework
for different platforms

6.  It is an efficient, flexible, and open-source
JavaScript library.
 It was developed and is maintained by Facebook.
 It is capable of rendering front-ends of web apps
that are simple, speedy, and scalable.

7.  Virtual DOM
This characteristic of React helps to speed up the app development process and
offers flexibility. The algorithm facilitates the replication of a web page in React’s virtual
memory.
 JavaScript XML or JSX
It is a mark-up syntax that describes the appearance of the interface of the app. It
makes the syntax just like HTML and is used to create React components by developers.
 React Native
Uses native, rather than web components to facilitate native React JS development
for Android and iOS.
 One-Way Data Binding
This means that React uses a flow of data that is unidirectional, forcing developers to
use the call back feature to edit components, and preventing them from editing them directly
 Declarative UI
This feature makes React code more readable and easier to fix bugs. React JS is the best
platform to develop UIs that are both exciting and engaging not just for web apps, but mobile
apps as well.

8.  If your developers are experienced in JavaScript
 If you’re planning to create an application that is
highly interactive
 If you’re all set to use the same framework for
different platforms

9.  Vue.JS web is an open source progressive JavaScript
framework used to develop interactive web interfaces.
 It is one of the famous frameworks used to simplify
web development.

requirement

12.  Spring was created back in 2002.
 Since then, Spring has gone through several
rounds of development and it is one of the best
choices for a Java-based framework.
 When it comes to making Java a relevant platform
for cloud computing, there’s hardly any other
framework as good as Spring

13.  Predefined Templates
Spring framework provides templates for JDBC, Hibernate, JPA etc. technologies.
So there is no need to write too much code. It hides the basic steps of these technologies.
 Loose Coupling
The Spring applications are loosely coupled because of dependency injection. The
Dependency Injection makes easier to test the application. The EJB or Struts application
require server to run the application but Spring framework doesn't require server
 Lightweight
Spring framework is lightweight because of its POJO implementation. The Spring
Framework doesn't force the programmer to inherit any class or implement any interface. That
is why it is said non-invasive
 Fast Development
The Dependency Injection feature of Spring Framework and it support to various
frameworks makes the easy development of JavaEE application.
 Powerful abstraction
It provides powerful abstraction to JavaEE specifications such as JMS, JDBC, JPA and
JTA.

14.  When you’re working on an enterprise software
development project and JVM is the preferred
language
 When you’re on your way to building a large scale
application that is CPU-intensive

15.  Express.js is a Server-Side, Model-View-Controller
(MVC) Web Framework.
 TJ Holowaychuk created Express.js in 2010 as the first
stable version.
 This is heavily influenced by the minimalistic
Framework Sinatra and offers minimalistic
functionality for lightweight software.

16.  Faster Server side development
Express.js provides many commonly used features of Node.js in the form
of functions that can be readily used anywhere in the program. This removes the
need to code for several hours and thus saves time.
 Middleware
Middleware is a part of the program that has access to the database, client
request, and the other middle wares. It is mainly responsible for the systematic
organization of different functions of Express.js.
 Routing
Express.JS provides a highly advanced routing mechanism which helps to
preserve the state of the webpage with the help of their URLs.
 Debugging
Debugging is crucial for the successful development of web applications.
Express.JS makes debugging easier by providing a debugging mechanism that has
the ability to pinpoint the exact part of the web application which has bugs.

17.  If your web development team masters in
JavaScript and aces Node.js based back-end
development
 If server less computing is your forte

18.  Developed back in 2010 by Armin Ronacher,
Flask is a micro-web Python-based framework.
 Since Python is currently a top-performing
programming language worldwide, the
popularity of Flask is increasing heavily

19.  Flask is not an end-to-end web development framework
 Flask uses Jinja2 as its template engine and Werkzeug for
HTTP handling purposes
 Flask is server-side rendered and a micro-web framework
 Can build a very basic application with the least numbers of
features
 set to use server less computing
 Can integrate with python.

20.  If you’re building a very basic application with the
least numbers of features
 If you’re all set to use server less computing
 If your app needs a Python integration

21.  Ruby on Rails is a server-side web application
development framework written in Ruby language by
David Heinemeier Hansson.
 It allows you to write less code than other languages
and frameworks.
 It includes everything needed to create database-
backed web applications according to MVC pattern.

22.  Symbol Garbage Collector
Passing symbols opens the possibility of several attacks in your system. The symbol
garbage collector collects the symbols which prevents your system from several attacks.
 Module #prepend
It allows you to insert a module in front of the class it was prepended.
 Keyword Arguments
It supports keyword arguments which helps to reduce memory consumption by Rails
application.
 Action Mailer
New methods deliver_now or deliver_later are used instead of #deliver and #deliver!.
 Rails API
It allows you to generate API and cleans all the middleware which is not necessary for an
application.

23.  If you’re looking for a high-speed development
process
 The development team masters Ruby language or
is willing to learn it

24.  Laravel is a PHP-based development framework
created in 2011.
 Taylor Otwell developed this framework that is a
server side framework and supports the MVC
architecture.
 In fact, Laravel believes in the Ruby on Rails
framework to a large extent and emphasizes the
developers’ experience during app development.

25.  Creating authorization and authentication systems
Every owner of the web application makes sure that unauthorized users do not access
secured or paid resources. It provides a simple way of implementing authentication. It also
provides a simple way of organizing the authorization logic and control access to resources.
 Integration with tools
Laravel is integrated with many tools that build a faster app. It is not only necessary to build
the app but also to create a faster app. Integration with the caching back end is one of the
major steps to improve the performance of a web app. Laravel is integrated with some popular
cache back end such as Redis, and Memcached.
 Mail service integration
Laravel is integrated with the Mail Service. This service is used to send notifications
to the user's emails. It provides a clean and simple API that allows you to send the email
quickly through a local or cloud-based service of your choice.
 Handling exception and configuration error
Handling exception and configuration errors are the major factors on the app's
usability. The manners in which the software app handles the errors have a huge impact on the
user's satisfaction and the app's usability. The organization does not want to lose their
customers, so for them, Laravel is the best choice.

26.  In an enterprise set-up with complex applications
 In large scale companies demanding scalable
applications

27.  Django was developed back in 2005 by Adrian
Holovaty and Simon Willison.
 It is another Python-dependent framework on our list
that is most comfortable with the MTV architectural
pattern.
 In recent times, Python is becoming more and more
popular. This is a major reason why Django is being
used by lots of developers across the world.

28.  Rapid Development
Django was designed with the intention to make a framework which takes
less time to build web application. The project implementation phase is a very time
taken but Django creates it rapidly.
 Secure
Django takes security seriously and helps developers to avoid many
common security mistakes, such as SQL injection, cross-site scripting, cross-site
request forgery etc. Its user authentication system provides a secure way to
manage user accounts and passwords.
 Scalable
Django is scalable in nature and has ability to quickly and flexibly switch
from small to large scale application project.
 Fully loaded
