The document outlines an introduction to the MEAN stack, which comprises MongoDB, Express.js, Angular, and Node.js for building web applications with JavaScript. It discusses the advantages of using MEAN stack, including scalability, a single-language approach, and flexibility in managing data. Key features of each component are highlighted, such as MongoDB's document-oriented storage, Express's middleware capabilities, Angular's component-based architecture, and Node.js's efficiency in server-side application development.

5. Mongo DB
Mongo DB is the world’s leading NoSQL database that
stores its data into a JSON (JavaScript Object Notation)
format.
MongoDB provides high performance data
persistence because it supports the
embedded data models that reduces I/O
activity on database system.
01
Mongo DB is document oriented database
designed for storing and retrieving data in
the form of documents. Each record in
MongoDB is a document.
02
MongoDB provides horizontal scalability
as part of its core functionality. Automatic
sharding distributes data across a cluster
of machines.

6. Express
Express is a minimal and flexible Node.js web application
framework that provides a robust set of features to
develop web and mobile applications.
Allows to set up middlewares to respond
to HTTP Requests01
Defines a routing table which is used to
perform different actions based on HTTP
Method and URL.
02
Allows to dynamically render HTML Pages
based on passing arguments to
templates.

7. Angular
Angular is a platform that makes it easy to build
applications with the web. Angular empowers developers
to build applications that live on the web, mobile, or the
desktop.
Component-based architecture that
provides a reusability and higher quality of
code01
Typescript provides better tooling, cleaner
code, and higher scalability

8. Node JS
Node.js is a cross-platform runtime environment and
library for running JavaScript applications outside the
browser. It is used for creating server-side and
networking web applications.
Node.js is highly scalable because event
mechanism helps the server to respond in
a non-blocking way.
01
Node.js is built on Google Chrome's V8
JavaScript Engine, so its library is very
fast in code execution.
02
Node.js has an open source community
which has produced many excellent
modules to add additional capabilities to
Node.js applications.

10. ADVANTAGES
Scalable
Create scalable applications that
are optimized for cloud deployment
Deployment
Simplify deployment with a built-in
web server
Single Language
Single language is used in the
whole application
Flexibility
