Choosing which web app languages to learn is the hardest part when you are just starting. Whether for web app development or choosing the technology stack for your product, it will be tough. There are more and more of them, and each one has its own programming challenges and steps. Many companies that make web apps have switched to a multi-lingual strategy because it gives them better performance, more flexibility, and the ability to work with other languages. Because of this, companies want to hire developers who can use more than one language.

An Overview of Web App Development Languages

When we talk about the best programming languages for making web apps, it’s important to remember that they all have some things in common. Business and web app development services have not suddenly changed how they use or try to use a certain programming language.

Even so, there’s no denying that the times are changing. In the world we live in now, even people who don’t write code need to know something about it. If you are curious about web app development, you should learn about the best programming languages for making apps. In this first part of the lesson, we’ll talk about what a programming language is all about.

What is a programming language?

Through a programming language, individuals can direct a computer to execute specific tasks. Instead of relying on binary, which is complex for humans to comprehend and write, we utilize languages that are more human-friendly. Code composed in these languages is then transformed into “machine code,” a language that computers can readily interpret and execute.

A web programmer

In essence, a programming language is a structured language containing a series of instructions that generate various types of output. These instructions serve to convey algorithms to a computer or other computing devices. When people discuss “programming languages,” they often refer to high-level languages like BASIC, C, C++, COBOL, Java, FORTRAN, Ada, and Pascal.

However, the landscape of programming languages has undergone significant evolution. As of 2024, the most prevalent languages for web content are English, accounting for nearly 59 percent of websites, followed by Russian and Spanish. In the domain of software development, JavaScript and HTML/CSS reign supreme as the most utilized programming languages, with over 63.6 percent of developers employing JavaScript and approximately 53 percent using HTML/CSS.

In the realm of web app development, languages such as Python, SQL, and TypeScript have also gained traction. Python, for instance, is widely favored for its readable syntax, extensive community support, and reusable code. Its built-in modules aid in automation testing and eliminate redundant manual tasks, making it a favorite among testers and developers.

Furthermore, the global market for web application development is poised to reach $179.90 billion in 2024. Contemporary frameworks and tools like React, Angular, and Vue.js are increasingly being leveraged for web application development. These frameworks offer numerous benefits, including expedited software development cycles, heightened efficiency, and simplified maintenance.

How does it work?

Each programming language has its own set of keywords and syntax, or rules for how to put program instructions together. These instructions are written in the programming language used to create the program, while statements are written in machine code, a different programming language. Machine code is a binary format consisting of ones and zeros, or 1s and 0s, with each digit representing either an instruction or some data in the program.

When a programmer types a command into their computer’s terminal, these instructions are transferred to the computer’s processor. Here, they’re converted into machine code so the computer can execute the programmer’s instructions. The resulting information is then translated back into a language that people can understand, typically English.

According to a report by Statista, as of 2022, JavaScript and HTML/CSS were the most commonly used programming languages among software developers worldwide, with more than 63.6 percent of respondents stating that they used JavaScript and around 53 percent using HTML/CSS. This trend is expected to continue into 2024, with JavaScript remaining a top choice for web app development.

The global web development market, valued at $60,709.6 million in 2022, is projected to reach $96,748.41 million by 2028, growing at a CAGR of 8.08%. This growth underscores the increasing importance of choosing the right web app language for your project.

Are web app languages different from other programming languages?

Yes, web app languages are indeed different from other programming languages, although there can be some overlap. Web app languages are a subset of programming languages that are specifically used to create dynamic, interactive systems that are accessed via a web browser.

As of 2022, JavaScript and HTML/CSS were the most commonly used programming languages among software developers around the world, with more than 63.6 percent of respondents stating that they used JavaScript and just around 53 percent using HTML/CSS3. This trend is expected to continue into 2024, with JavaScript remaining a top choice for web app development.

For instance, Python has been gaining popularity due to its readable syntax, vast community support, and reusable codes. Its built-in modules help with automation testing and eliminate repetitive manual tasks, making it popular among testers and developers.

On the other hand, JavaScript, HTML, and CSS have a never-ending demand in this market as they are the basics of web development. Another language named TypeScript has captured the market because of its scalability and readability.

In conclusion, while all programming languages share some commonalities, web app languages have their own unique features and use cases. Understanding these differences is crucial for choosing the right language for your web app development project in 2024.

7. SQL

SQL, short for Structured Query Language, stands as a cornerstone language in the realm of web development. Originating from the ingenuity of IBM computer scientists in the 1970s, SQL has since matured into a ubiquitous language for navigating and administering databases. As of 2024, SQL commands a staggering 40% adoption rate among developers worldwide, securing its position as the 4th most favored language according to the esteemed TIOBE Index.


SQL furnishes developers with a versatile toolkit, enabling them to execute an array of operations against databases, ranging from querying data to managing records. Since its inception in the mid-1970s, SQL has reigned as the foremost data manipulation language, enjoying preference from a substantial 67% of database administrators.

In the landscape of web development, SQL assumes a pivotal role in fashioning dynamic websites that seamlessly interact with databases. To embark on the creation of such websites, a confluence of essential components is imperative: an RDBMS database program (e.g., SQL Server, MySQL, or PostgreSQL), a server-side scripting language (e.g., PHP, ASP, or analogous languages), SQL for orchestrating data extraction and manipulation, and HTML/CSS for sculpting the structure and aesthetics of web pages.

At the heart of SQL lies RDBMS, or Relational Database Management System, which underpins its functionality. Prominent database systems such as MS SQL Server, Oracle, and MySQL operate on an RDBMS architecture. Within this framework, data finds organization within tables, each comprising columns and rows, culminating in a structured and efficient mechanism for storing and retrieving data.

8. PHP

PHP, short for Hypertext Preprocessor, emerges as a versatile open-source scripting language celebrated for its prowess in server-side scripting. Originating from the ingenious mind of Rasmus Lerdorf in 1993, PHP has since ascended to prominence as a cornerstone of web programming. As of 2024, PHP commands a noteworthy usage rate, resonating with 79.2% of websites whose programming language could be ascertained.


PHP empowers a diverse spectrum of functionalities, encompassing tasks such as form data collection, dynamic page content generation, and cookie management.
