6 Coding Languages Full-Stack Developers Should Know

As companies become more advanced in software development and deployment, web developers have become the most sought-after employees. According to the 2017 Stack Overflow Developer survey, of the 72.6% of recipients that responded as web developers, almost two-thirds of them (63.7%) identify as full-stack developers. This specific type of developer specializes in coding and managing every layer of software infrastructure, making them a one-man army for software development.

Coding for the entire infrastructure isn’t a simple feat, but full-stack developers have an easier time because they’re fluent in one or several complex coding languages. Throughout to the survey, over 30 coding languages are referenced by web developers. To narrow down the list, here are six coding languages that all full-stack developers should know.


Pretend a webpage is a house: if HTML is the house’s foundation, then CSS provides the aesthetics with the roofing, paint, windows, and doors. Hypertext Markup Language (HTML) is the standard language for creating web pages and applications, which maintains the web page’s existence. This language is one of the foundations of the Internet, and it combines with Cascading Style Sheets (CSS) to help create stylistic and informative web pages. HTML helps build the web page, and CSS enables the presentation and content. Full-stack developers should already know these languages by heart, and that they cannot have one without the other. These two languages are especially useful if they’re creating readable layouts and visual designs for an efficient User Interface.


JavaScript is becoming increasingly popular will full-stack developers, as it helps with features like node construction, revealing content in other layers, and building the infrastructure’s backbone. Coding with JavaScript enables developers to work with important language features such as functional composition to create more complicated functions, closures for continuation programming, and infrastructure visibility. This coding language is important for testing frameworks and building new interfaces, so developers should definitely know how to speak this language.


Structured Query Language (SQL) helps users communicate with various databases, and perform tasks such as update or retrieve data from said databases. Related languages like NoSQL and N1QL help full-stack developers support large numbers of concurrent users, limit network downtime between user ends, and handle unstructured data. SQL enables programmers to manage data easier, which helps build the code for infrastructure components.


Packaged software is typically designed by using C++, which is helpful for multi-device, multi-platform application development. C++’s greatest strength is its scalability, as developers can continuously integrate data to the applications. This language is great for producing software because of the option for constant integration, helping provide a positive user experience. Full-stack developers can benefit from C++ because of its ability to build and maintain complex applications, making this language vital for building advanced software. 


Python emphasizes code readability by scaling down the number of lines of code needed to produce functional programming. Certain portions of the application are sometimes time-critical, Python reintegrates languages like C++ to help with rapid development. If full-stack developers are working in DevOps-oriented environments, then Python is ideal for promoting speedy development. It’s simpler than C++, but it’s useful for integrating programs into applications like legacy networks.


Even though PHP isn’t as popular as other coding languages like Python or C++, it’s still a powerful legacy language. It’s compatible with all major operating systems like Linux and Microsoft Windows, and it gives full-stack developers the choice to code on an operating system and a web server. Developers can write database-enabled web pages with specific extensions, and it’s compatible with web development that uses HTML.
