Java Full Stack Vs. MERN Stack in 2024: Which one are You going to Choose?

I am definitely sure from when is announced about the features of Devin's software engineer, from then everyone is thinking about how to get a job as a Software Engineer. They are thinking their jobs are in danger. Because Devin is here to do their tasks. Devin’s features are unbelievable but do you ever think how a robot or a machine can do their task without humans? Impossible! this can't happen all machines depend on Humans. If someone doesn’t know how to code they don’t know how to create the front end of a website or an application and they do not know any type of programming language e.g., C, C++, Java, or Python then how can they interact with Devin like AI? So your jobs are not in danger but you have to work on your skills, you have to update according to technologies, you have to know how to use them and how to get them to work. 

So please don’t demotivate yourself and keep learning what you are learning. So now let’s discuss about trending stacks Java Full Stack and MERN Stack in 2024. I am sure if you belong to the coding world then you obviously have ever heard about these full stacks and some enthusiasts will be definitely learning one of them. So now we are talking about which one should we choose Java Full Stack or MERN Stack. For your kind information, I want to tell you both technologies are trending, both have their own benefit if you get expertise in one of them then you can get a job easily. Now I will discuss some advantages and disadvantages of both stacks then you can choose which is suitable for you.

So ok, let’s get started!!

First of all, you need to know what the stack is. A full stack is a composition of all technologies that you can use to build a Website or an application for example a website needs a database, web servers, operating systems, and the development environment etc. To be precise, a stack consists of programming language frameworks, tools, Libraries, and UI or US solutions software.

I would say that if any company creates websites or applications, so they must have expertise and employees who can incorporate that particular project. Furthermore, as technological stacks influence user experience and application functionality and also clients should be knowledgeable about them. Web development stacks provide us with comprehensive tools and technologies forming the foundational platform to aid in the creation of functional web applications.

What is Java Full Stack?

In Java full stack, Java will be the centred and primary programming language. I mean all front-end and back-end libraries will work with Java programming language. For being a Java Full stack developer you must know Java programming language.  

Java Full Stack typically utilizes Java-based frontend frameworks like JavaServer Faces (JSF), Thymeleaf, or Angular. These frameworks offer comprehensive features and robust tools for building front-end components, ensuring a powerful user interface.

Java provides numerous backend frameworks, Sping Boot is one of the most popular frameworks. This offers a comprehensive environment for creating scalable and robust web applications. Java Full Stack developers commonly work with relational databases such as MySQL, PostgreSQL, or Oracle Database, ideal for applications with intricate data relationships and ACID compliance. 

Java exhibits strong performance, particularly in server-side processing, owing to its utilization of multithreading, Just-In-Time (JIT) compilation, and efficient garbage collection mechanisms. Multithreading enables Java to handle concurrent tasks effectively, enhancing performance in multi-user scenarios. JIT compilation optimizes execution speed by translating Java bytecode into native machine code at runtime. Furthermore, Java's garbage collection efficiently manages memory, reducing memory leaks and enhancing application stability. These attributes collectively establish Java as a robust choice for high-performance applications, offering responsiveness, scalability, and reliability in demanding software environments.

Companies e.g., Oracle, IBM, Google, and numerous financial institutions use Java Full stack. It is potentially slower than the MERN stack due to verbosity, and prioritizes structured and maintainable code. Emphasizing readability and maintainability fosters robust and long-lasting codebases in Java projects.

What is MERN Stack?

In MERN full stack, Javascript will be the centred and primary programming language. I mean all front-end and back-end libraries will work with Javascript programming language. To be a MERN Full stack developer you must know Javascript programming language.MERN is abbreviated as M for MongoDB a database library, E for Express.js, R for React.js a front-end library and N for node.js a backend library. I am sure you already know this.   

Conversely, in the MERN stack, Node.js is single-threaded by default but can scale horizontally using clustering for concurrent requests. While the MERN stack benefits from a vibrant JavaScript/Node.js community. Each stack has its learning curves and scalability features, catering to different project requirements and developer expertise.

MERN applications excel in delivering high performance, particularly for single-page applications (SPAs) and real-time scenarios. This is attributed to Node.js's single-threaded architecture and React's efficient virtual DOM handling. However, performance levels are subject to code optimization practices. While the inherent single-threaded nature of Node.js contributes to responsiveness, React's efficient virtual DOM management further enhances performance. Nevertheless, the overall performance can fluctuate based on the effectiveness of code optimization strategies employed within the application.

Companies e.g., Facebook, Airbnb, Uber (React) use MERN stack for its rapid prototyping and development pace, facilitated by JavaScript's flexibility and the abundance of pre-built React components. JavaScript's versatile nature enables developers to swiftly iterate through various design iterations, while the extensive library of pre-made React components accelerates the development process by providing ready-to-use solutions for common UI elements.

Final words : 

I hope this information gives you an understanding of both full stacks. Now you can decide which one you can choose. But I want to suggest you both full stacks have their own scope, benefits, and features. One of them is fulfilling some particular requirement and the second one is not. That’s why don’t be so confused choose whatever you are learning. But still you are still confused, you can join any full stack web development course with Java stack or MERN stack, and then you will get a clear and practical knowledge of this.
