The 2023 Java Programmer RoadMap UPDATED by javinpaul Javarevisited

But you should still learn SQL and understand how relational databases work. I want to strongly agree with his recommendation that you learn a relational database. JavaScript can handle in a really easy way the DOM of a webpage. So, then you can learn how to select an element, with operations like getElementById, then to update a page when a button is clicked.

There is no other JavaScript library other than React which has taken the front-end ecosystem by storm in modern time. React is a library built and open-sourced by the smart people at Facebook. In React, developers write components for their web interface and compose them together. Always create projects, no matter if it’s small, but start creating projects and host them on GitHub. Each week create one project, find some trending ideas and execute it with your knowledge. I know it’s hard to start initially, but believe me, it will be easy once you practice.

Utility Libraries

While most of the work using JS is done on the front end of the web application, JS is not limited to it. Instead, you can also run it outside the browser using an extremely powerful runtime environment – Node.js. JavaScript Type Coercion is the process of automating the conversion of data value types, such as conversion from String to Number, Boolean to Number, and Number to String, according to the applied operator type. It is a high-level, multi-paradigm, just-in-time compiled language that has prototype-based object orientation, dynamic typing, and curly-bracket syntax. Donations to freeCodeCamp go toward our education initiatives, and help pay for servers, services, and staff.

They have a free 7-day trial so you can see if you like it, and I can also give you a deal where you can get $100 off of 1 year of their Basic Plan. If you’re fairly certain you want to get into web development, Team Treehouse is a great place to learn. One downside to freeCodeCamp is that while they do have an incredible curriculum with a built-in coding environment, they don’t have structured videos as part of it. One way you can think about this is that front-end web development is like the “front of house” part of a restaurant. It’s the section where customers come to see and experience the restaurant– the interior decor, seating, and of course, eating the food.

Coding Standards

It’s an initiative that aims to optimize Enterprise Java for Microservice Architecture. It’s driven by Eclipse, one of the leading organizations of Java and the company behind popular Eclipse IDE. Out of these Docker is the most important because it makes it easy to set up your development environment as well as it also makes the Deployment of Java Microservices easier.

  • In creating websites, a web developer writes its source code in one of the appropriate programming languages, following either the wishes of the customer or the layout of the designer.
  • I will also be talking about some example projects that you can build to practice your skills.
  • Java offers great APIs like Swing and Java FX for developing GUI clients.
  • I, too, learnt full-stack development last year, and you also can do the same.
  • Key considerations should include appropriate data preparation, thoughtful selection of analytics and data type, as well as level of complexity.

I have kept it simple so that most people can follow it and only included the important stuff. When I started learning Java, I started with books which were very hard to read, lengthy and boring but they had computer programs which I can copy and run. You can also build and deploy Java FX applications on Raspberry PI, one of the small but powerful computers. If you are interested in that, Frank Delporte has a great course Use Java and Java FX on a Raspberry PI for beginners. If you want to develop a GUI application like NetBeans, one of the famous Java editors which are also written in Java then you can learn Java FX in 2023.

Next, read up on the Sass preprocessor, an extension of the CSS language which adds syntactic improvements and encourages style reusability. Study the CSS methodologies mentioned above, and lastly, CSS modules. React-redux is an official React binding for Redux and is very simple to learn. In recent times, JavaScript has seen major improvements with lots of new features being added to the language making it more powerful. This roadmap is targeted at the freshers who are trying to understand front end. If you are already familiar with front end development and want to explore another perspective, then you are welcome to explore it.

The major problem we face is writing scalable and maintainable CSSS that also for different screens and devices. To make it easier to work with it, over time, experienced frontend developers have designed methodologies to guide people on how to write organized CSS for complex projects, such as using SMACSS, BEM, SUIT CSS, etc. During the last years, JavaScript becomes one of the most potent and most used programming languages, it’s used in web, game, desktop development, and much more. Quarkus is one of the promising frameworks for Java developers.


It’s fast, free, easy to use, and you can customize it with themes and extensions. “Front end” means that you’re dealing mainly with the client side. It’s called the “front end” because it’s what you can see in the browser. Conversely, the “back end” is the part of the website that you can’t really see, but it handles a lot of the logic and functionality that is necessary for everything to work. The terms “front end,” “back end,” and “full stack” web developer describe what part of the client/server relationship you’re working with.

TypeScript provides static typing, that allows you to catch errors earlier in the debugging process. It also saves your time as it finds bugs before the code runs. This is useful, for example, when we need to submit a form or get a user’s information. Here’s a full YouTube course on how to get your site online that covers the entire process from start to finish. But now, it’s super easy and you can use tools like GitHub Pages, Netlify, or Vercel. Once you have your website, you need to put it on the internet, so people can see it.

More sophisticated preparation will both aid and amplify the analysis efforts. Key considerations should include appropriate data preparation, thoughtful selection of analytics and data type, as well as level of complexity. As with any analytics initiative involving student data, there is always the possibility for unintended consequences to surface, and it is expected that these have been addressed throughout the process.

Deployment is the process of deploying your code to a hosting platform. Responsive websites are sites that look good and are usable on all devices or screen sizes. You probably know how important it is to build a responsive website, as people use so many different devices these days. You should learn what it is, and some of the basic commands like how to move around directories, how to create a new directory, or how to create a new file.

The Dangers of Relying Too Much on Frontend Frameworks – A Short Story

98% of websites as of 2022 use JS on the front-end/client-side for the webpage behavior. Here, you need to how to build a RESTful API and you can use MongoDB when working with databases. Which is quite simple to learn when you already know JavaScript. After that, you will want to build even more difficult applications like a Job Search tool, a blog, or a Document page.
