Promosys offers MEAN Stack training / Mean Training course by the leading industry expert trainers and ensures your mastery of full MEAN Stack development. Take your career to the next level by acquiring this MEAN Stack program from our institute which proves that you are an expert at JavaScript technologies of the most popular MEAN Stack.

MEAN is an acronym for MongoDB, Express.js and Angularjs, all of which function upon Node.js. This is a platform that allows one to build applications using code as less as possible. Moreover, writing the complete code from client to server using only JavaScript is like a dream come true for beginners Mean Training who want working apps in a short period of time.If you are looking to join Mean stack course in Lucknow then Promosys Technology will be the best Institute for providing MEAN Stack training in Lucknow

The name “MEAN” is, in fact, an acronym for the four technologies that comprise the stack: MongoDB, Express.js, AngularJS, and Node.js. It was first coined by MongoDB developer Valeri Karpov in a 2013 blog post on the MongoDB website, where he explained the advantages of using the four technologies in full stack web development.

Simply put the four technologies in the MEAN makes full stack development uniform, because the four technologies involved the use, to some extent, the JavaScript programming language: AngularJS, Node.js and Express.js are all frameworks based on JavaScript, while MongoDB stores data in a format similar to the one used by JavaScript to store data. Therefore, full stack development with the MEAN stack becomes seamless and feels unified, and using it leads to performance gains and reduction in development time and subsequently, development costs.

  •   MongoDB  :  MongoDB is a database program and is among the most popular NoSQL databases, which are databases that store and model data in structures other than the tables used by relational databases such as MySQL. As opposed to the tabular structure of relational databases, MongoDB, being a document-oriented database, stores data as documents, which encapsulate all associated information corresponding to a specific database object.
    As such, MongoDB offers many advantages over relational databases: it offers a clearer structure for each data object, allows for smoother scaling of projects, and offers performance improvements due to its faster data access times. Moreover, since it stores data in a format very similar to JSON, which is the data format used by JavaScript to store objects, it is easily connected to and readable by programs, especially those based on JavaScript.
  • Express.js  :    
    Just as there are many frontend frameworks for JavaScript to make the lives of developers exponentially easier, there are also backend frameworks for it. Express.js is a framework for Node.js, meaning it builds on top of the base language to provide developers with a rich set of features commonly used in web and mobile applications. It is the de facto framework for Node.js, meaning in practice, most of the developers who use Node.js for backend development also use the Express.js framework.
  •   AngularJS  :  AngularJS is the only technology in the stack that’s part of the frontend component. It’s a framework for JavaScript, which controls the behavior of all the different elements that are displayed on web pages and are visible to viewers. AngularJS makes client-side scripting faster and more convenient by adding important functionalities to the base language, such as two-way data binding, automatic form validations, and the ability to create reusable HTML components using directives.
  •   Node.js  :  Node.js is a JavaScript runtime environment, meaning it allows JavaScript code to be executed on the server side, where it can access and send instructions to the computer’s processor and memory. JavaScript was initially a purely client-side scripting language, meaning it could not be used to write backend codes, which are executed on the server side. Node.js expanded JavaScript’s power further by giving it server-side capabilities, and whereas JavaScript used to be restricted to the frontend component, Node.js extended its power to the backend world, thereby giving rise to the JavaScript full stack developer.
    The most obvious advantage offered by Node.JS is uniformity of frontend and backend languages: since the same language can be used for both, it practically abolishes the wall that divided the two segments of web development. This directly translates to quicker and cleaner development. Moreover, it enables asynchronous programming, meaning it can perform independent processes without waiting for other processes to finish. This allows the program to scale to a large number of users, leading to large performance improvements compared to synchronous programming.
