Any experienced back-end engineer can see the constraints that this lack of maturity brings to the task, especially when compared to more established options like PHP or Java. JavaScript development will also enrich your project if you aim to get an interactive and scalable website. MongoDB is a NoSQL database program that uses the JavaScript Object Notation (JSON) format.

In this way, the resulting apps will be capable of running several independent procedures simultaneously. There is no doubt about the fact that JavaScript is an extremely popular programming language right now. The reason for this is that JavaScript seems to be everywhere, particularly propelling the World Wide Web. Besides being a core component of lots of web applications, it also enables interactive elements on the web. Instagram, Mozilla, Bitbucket, and NASA’s website are all powered by this Python-driven environment.

Disadvantages of JavaScript development

There are also a number of back-end frameworks and libraries that can make development easier, such as Laravel and Express. Back-end development is responsible for all of the behind-the-scenes functionality. This includes things like database management, server administration, and API development. In the ever-growing and constantly changing world of technology, full-stack development is becoming an increasingly important skill to have. The idea of “Full Stack JavaScript” is that all software in a web application, both client side and server side,
should be written using JavaScript only. As mentioned in the introduction, JavaScript added its server-side capabilities after being focused exclusively in the frontend.

This can simplify your development process, reduce the learning curve, and increase your productivity. You can also reuse code, libraries, and frameworks across the front-end and the back-end, which can save time and resources. Additionally, JavaScript is a widely used and supported language, which means that you can find a lot of resources, documentation, tutorials, and community support online. JavaScript is also a flexible and dynamic language, which allows you to create interactive and responsive web applications. A “Stack)” is a set of programming languages, technologies, or software products.

As we mentioned earlier, many large and successful tech companies have already applied a full-stack JavaScript, so there is nothing to afraid of. Such giants as Airbnb, Netflix, eBay and Google will unlikely choose the technology that performs poorly. All of these companies adopted a full stack JS framework for the web development. So, if you still doubt about opting for this approach, learn their success stories. All the technologies needed for a full stack JavaScript development are open-source, meaning that they can be used by anyone for free. Due to this, a development team has an opportunity to take advantage of the large pool of use cases that already exist.

This, basically, means that the objects stored in a database are identical to the objects a client JavaScript sees. So, the “birth” of Node.js is a major event that made a full JavaScript development possible. If you already know the language, consider taking on a framework or library.

Being initially bound to front end engineering, the language has seen even more growth in popularity after an ability to use it on the server side was represented. Ever since there has been a heated discussion going on about the use of full stack JavaScript — with MEAN and MERN being its most popular software stacks. So, now that we know what full stack JavaScript is and what is has to offer, let’s learn what a software engineer needs to know to be considered a full stack JavaScript web developer. There are definitely pros and cons to using JavaScript in the full stack of the application. Here are some to help you think about whether or not a JavaScript tech stack is right for you or your team. Full-stack developers are able to create seamless experiences across all channels and devices, which is essential for providing a consistent customer experience.

Full Stack JavaScript Benefits

Node.js, Express, React, and MongoDB are some of the most popular and widely used ones. Node.js is a runtime environment that runs JavaScript on the server-side, and is based on the Chrome V8 engine which is both fast and efficient. Express is a web framework for Node.js that provides a simple and elegant way to create web applications, being lightweight and modular. React is a front-end library for creating user interfaces, using a component-based architecture and virtual DOM for improved performance. Finally, MongoDB is a document-based database that stores data in JSON-like format, integrating well with Node.js and Express while offering features such as indexing, aggregation, and schema validation. One of the main benefits of using JavaScript for full-stack web development is that you can use the same language for both the front-end and the back-end.

General Coding Knowledge

Simply put, this means that multiple independent processes can run simultaneously. Consequently, web applications built with full stack JavaScript perform better and faster that results in the improved user experience. For quite a long time, programmers had to use another language for the server-side scripting. However, such situation changed in 2011 when Node.js was introduced. A full stack JavaScript developer is able to work with code in the backend and in the frontend to build a web app, all using JavaScript.

Full Stack JavaScript Benefits

Since all of these programs are in JavaScript so Mean applications can be written in one language for both server-side and client-side execution environments. With all this, we should be able to create a REST API that connects to a database, performs read and write operations, and returns the data to the client. But for it to be online and anyone can access it, we need to upload it to a hosting service, the most used in Node is Heroku, it’s free, I recommend that you learn it and upload your applications there. Then create an account on GitHub, it’s free, and it will be very useful for uploading projects from your computer to the cloud, which in git is known as a remote repository. Even though JavaScript is more than 20 years old, the technologies that have been developed are still a bit immature. It will take time for developers and programmers to fully utilise and employ these technologies and put it to good use for application development efforts.


When errors do occur, a product designed with error tolerance in mind can help users recover quickly. For example, a clear error message or an easy-to-access undo button can encourage users to continue using the product or service. People have different sensory abilities, so making information and feedback perceptible—or available in multiple formats—is a crucial aspect of inclusive design. Simplicity and intuitiveness relate to the usability of a product or service.

It is also written in JavaScript, so you won’t have to learn a new language. But you can learn to write back-end code in Python, Ruby, PHP, or C#. There are also web development frameworks for back-end code, and it definitely helps to know those also. Any developer should also learn version control, and the most popular version control system is Git.
