Still confused? Then consider reading this article to get an overview, and by the end you will definitely come up with a conclusion.
Before jumping on to answer the question in the title, let us look at what defines them.
Most full-stack developers focus on some internal programming language, such as Ruby, PHP, or Python. However, some people, primarily if they work as developers for a long time, will use more than one language.
Some full stack developers, especially in 2019, also learn project management, visual design, web design, or user interaction skills to complete their "stack" as needed.
With the blurring of the front-end and server-side boundaries, more and more developers are turning to the so-called "full-stack." Many employers (especially those that work with different types of websites) are looking for developers who know how to handle all parts of the website so that they can use the best tools to get the job done, whether it's a technical "user interface" or not or "back-end." Therefore, the emergence of a fully developed company based on job requirements.
Contrary to what many people think, "full-stack" does not necessarily mean that developers will write all the code for the site themselves. Many full-stack Web developers spend most of their time at the beginning or end of website code.
But the point is that they have enough knowledge of all the code stacks that can be used anywhere. Some full-stack developers program the entire website, including front-end and back-end, but usually, only they are self-employed or the only developers working on the project.
In other words the idea is that full-stack developers can cross-reference the entire technology "stack". Full stack developers provide a complete package.
The user interface (or Web or mobile application) is when the user sees and directly interacts with the user interface. Its structure language such as:
Although the front-end is everything the user interacts with directly, the back-end is behind the scenes, which has some advantages compared to the project-specific front-end technology.
Backend developers usually work with front-end developers to make their code work on the site or application design.
