Most online courses for machine learning and AI nowadays provide knowledge of MERN stacks. It is a Javascript Stack that allows a coder to easily deploy full-stack web applications. The MERN stacks are a combination of four technologies that make up the acronym. These technologies are MongoDB, Express, React, Node.

js that make the development process easier and faster. Any of these technologies provide an end-to-end framework to the developer to develop suitable web applications easily. To start the MERN stack development one needs to first understand its four technologies in detail and their uses.
MongoDB
Any MERN stack training provides knowledge and skills to handle this cross-platform database that is documentation-oriented. MongoDB is essentially a NoSQL database that contains every record as a document. This document consists of the key-value pairs of JavaScript Object Notation or JSON objects. It is a flexible database that helps create databases, schemas, tables, and more. The documents are the basic unit of the MongoDB that helps use the Mongo shell as well through the JavaScript interface. It helps the professional to carry out various operations like updating and deleting records, querying on various topics, and interact with the users.
Express
This is a backend framework that is present in Node.js. Any online courses for machine learning and AI provide knowledge to use this framework to write code as Node modules.

It helps the coders to design any APIs and other web applications. Express also allows development support through a host of middleware that helps write shorter codes to save time while ensuring quality. Express is mainly used as it is single-threaded, asynchronous, efficient, scalable, and allows reusability of the code. It is a robust API that has the biggest community of online support for Node.js.
React
This is a JavaScript library that helps build interfaces. Its knowledge is provided at any MERN stack training to easily develop single-page, mobile, desktop, and other web applications. It is the best tool to create applications that can handle any amount of rapidly changing data. The code format is JavaScript that is one of the most common coding languages to create UI components globally. It allows the creation of a virtual DOM to help modify the application and render to see changes without causing changes to the original DOM. The JSX script is easy to write and manipulate.
Node.js
This JavaScript runtime environment allows the developer to run the code outside the browser but on the server. Any online courses for machine learning and AI is not complete without knowing about Node.js that allows one to choose thousands of free packages. It is an open-source runtime environment in JavaScript that follows a single-thread model for data streaming. The JavaScript Engine allows for faster code executions while being completely integrated with Google Chrome. It is a highly scalable environment that can be used for a variety of applications and product developments to write every kind of code requirement.
