A full-stack developer is a person who can design, write, test and deploy code as well. That means full-stack developers must become experts in many different programming languages in order to build their projects from scratch. Full-stack developers are specialists in various stages of the web development process, which is why they have more job opportunities across different companies.

Advantages of Full Stack Developers:

Low cost development
Fast application development
Easy technology upgrades

There are many different web development stacks that developers use to become full-stack web developers. Here are the best web development stacks used by top companies and startups.

1.MERN Full Stack

MERN Stack is a full-stack JavaScript framework for web development. It combines the power of MongoDB, Express, React.js, and Node.js to create a fast and robust backend for web applications. MERN stack is a one of the most popular web development stack.

Important technologies to become a MERN Stack Developer:

React.js: React is a declarative, efficient, and flexible JavaScript library for building user interfaces.
MongoDB: MongoDB is a document-oriented database system. Documents are minimally structured objects that can be queried and indexed in various ways. Although designed for storage and retrieval of large amounts of data, MongoDB also supports operations for adding new data and removing
Express.js:Express.js is an open-source web application framework running on Node.js that provides a robust set of features for developing web applications and APIs.
Node.js: Node.js is an open-source, cross-platform JavaScript run-time environment for developing server-side web applications. Node contains libraries for building fast and scalable network applications.
Redux(Optional):Redux is an open-source JavaScript library for managing applications state.(You can use context hooks)

2.MEAN Full Stack

The Mean Stack is a development platform based on Node.js, Express.js, MongoDB and AngularJS that integrates these technologies in order to build efficient back-end web applications.

Important technologies to become a MEAN Stack Developer:

AngularJS: AngularJS is an open-source JavaScript front-end web application framework. One of its primary functions is to assist with creating single-page applications which have a decent in browser user experience.
MongoDB: MongoDB is a document-oriented database system. Documents are minimally structured objects that can be queried and indexed in various ways. Although designed for storage and retrieval of large amounts of data, MongoDB also supports operations for adding new data and removing
Express.js:Express.js is an open-source web application framework running on Node.js that provides a robust set of features for developing web applications and APIs.
Node.js: Node.js is an open-source, cross-platform JavaScript run-time environment for developing server-side web applications. Node contains libraries for building fast and scalable network applications.
Redux(Optional):Redux is an open-source JavaScript library for managing applications state

3.MEVN Stack

MEVN is an acronym for MongoDB, ExpressJS, Vuejs and Node.js. MEVN is a high-performance stack that provides a full set of tools for building modern web apps.

Important technologies to become a MEVN Stack Developer:

Vue.js: Vue.js is a very fast, lightweight, and flexible JavaScript library for building user interfaces.
MongoDB: MongoDB is a document-oriented database system. Documents are minimally structured objects that can be queried and indexed in various ways. Although designed for storage and retrieval of large amounts of data, MongoDB also supports operations for adding new data and removing
Express.js:Express.js is an open-source web application framework running on Node.js that provides a robust set of features for developing web applications and APIs.
Node.js: Node.js is an open-source, cross-platform JavaScript run-time environment for developing server-side web applications. Node contains libraries for building fast and scalable network applications.

4.LAMP Stack (PHP Full Stack)

Lamp Web Development stack is a term referring to a collection of software that is used together to build websites. This includes the LAMP development stack, which consists of Linux, Apache, MySQL and PHP.

Important technologies to become a LAMP Stack Developer:

PHP: PHP is a scripting language that serves as the base for web development. It's most often used to embed PHP code into HTML files so that the web server can understand and process it.
MySQL: MySQL is a database server, or a program used to create databases. It can be described as a system that enables users to read and write data in tables.
JavaScript: JavaScript is a programming language that is often used to make web pages interactive. Usually, JavaScript programs are used to change the contents of the page based on a user's action.
JQuery: This is a library that’s popular for its easy-to-use interface and cross-browser compatibility. The jQuery library enables developers to interact with the DOM using selector syntax, modify the DOM object as necessary.

5. Python Full Stack

Python is a programming language that can be used on both sides of the stack. It can be used for your data analyzing, your backend scripting and as a web framework. Now python is used for most Machine Learning Applications, Analytics applications, and Finance applications because python provides useful libraries to build those applications

Important technologies to become a Python Stack Developer:

Python: Python is an easy-to-learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-orientated programming.
MongoDB or MySQL
React or AngularJs
Flask or Django
