8 Most Popular Programming Languages for App and Web Development

The technology world is evolving with time and programming languages are taking the front seat in the world. Many best programming languages are now utilized for Web Development, Machine Learning, Data Science, etc. In addition, the popularity of programming languages has raised the demand for job opportunities and applications. 

Behind every software, web, and digital application that we use nowadays, the most hidden and significant feature is their programming language. Therefore, every web developer or mobile app development company needs to stay updated on the latest business trends and should be informed about the latest, emerging, top, and most popular programming languages.

If you want to choose the most popular programming language for your project requirements and objectives, you can have a look at the few best programming languages ruling the industry. Let’s get started by understanding what a programming language is.

What is a Programming Language?

Programming is a set of instructions provided to a computer to execute it. Computers understand and think in binary strings 1s and 0s, and because of this, programming language interprets into something that humans can understand. A programming language is a set of instructions, command lines required for the development of a program.

Programmers write code in a high-level language. The computer hardware recognizes it when this code is compiled into a low-level language. Programming languages ​​are classified into two levels: low-level and high-level programming languages.

Low-level programming languages are quite similar to binary code. As a result, they are more difficult for humans to read, although they are easier than 0 and 1. The advantage of low-level languages ​​is that they are fast and work just like a PC does.

High-level programming languages ​​are similar to the way people communicate with each other. They ​​use similar words that we use in our everyday life. This suggests that they are easier to program than low-level programming languages, although more work is required to translate them into machine code.

The runtime difference between high-level and low-level programming languages ​​is usually milliseconds. High-level languages ​​work in most cases.

Types of Programming Languages

Types of Programming Languages

Let’s have a look at different types of programming languages:

Procedural Programming Languages

The procedural functions can manage the variables except for the value returns for these functions. The programming worldview derived from structured programming defines a series of well-organized systems and stages of program development. This type of programming performs a series of statements that initialize the result. 

For the most part, this type of programming makes use of variables, heavy loops, and some other elements, which is moreover a major difference among procedural and functional languages. It provides a set of instructions that break down a program into functions, constraint statements, declarations, and variables.

Various programming editors or IDEs help clients develop programming code using at least one programming language. Some popular and widely used examples of procedural programming languages: Pascal, Java, BASIC, FORTRAN, etc.

Functional Programming Languages

Functional programming is usually utilized for storing the information, often evading loops in recursive functions support. This type of programming language also emphasizes the return values ​​of functions and also has a side effects section.

Functional programming configuration is a lambda calculus with recursion to perform computations and limited assignment matching. It does not support iteration like loop statements and conditional statements such as “if-else”.

In functional languages, it is easy to understand the emotional problems in their programming model, which is confusing to them. However, the program code is decoded in machine language, which is also a problem for wireframe programming. You can initiate some algorithmic calls and change query parameters.

Object-oriented Programming Languages

The main principles of object-oriented programming languages are encapsulation, expressing everything that is required. Object-oriented programming systems (OOPS) provide many features such as inheritance, encapsulation, polymorphism, abstraction, classes, and objects. This type of programming language thinks about a problem and then breaks it down into a set of objects, offering a solution to any particular problem.

Most of the languages ​​with many representations in the world are object-oriented programming languages ​​such as Python, JavaScript, Java, C ++, C # and this is just the beginning. This programming language processes information as a collection of internal and external information. Encapsulation is a key principle as it provides secure code.

Scripting Programming Languages

A script or scripting language is a type of programming language that offers an exclusive run-time setting that robotizes the execution of the task, these are similar to the assignments that are then again executed by some human administrator. Operators combine for run conditions and create plugins and extensions for existing applications. Scripting is usually procedural. 

Most of them consist of a few object-oriented language elements yet have their category as they are not developed languages for huge systems development support in general. Language in system administration, web applications, gaming applications, and interactive media. Instead of compiling, it interprets programming languages ​​over time.

Logic Programming Languages

This type of programming language is centered on formal logic. This means that it still won’t ask the machine to do anything, it uses the constraints on what it has to consider. Logic languages ​​are easier to program in C in an object-oriented way.

In fact, many languages ​​include features and goals from different areas that support the increased vitality of this type of language. However, many programming languages ​​are incompatible with other types of languages. PROLOG, Answer Set programming (ASAP), and Datalog are important logic programming languages ​​whose rules are declared in classes.

Top 8 Programming Languages for Web & Mobile App Development

The demand for the top most popular programming languages is continuously changing each year because of the development of the most innovative applications worldwide. There are nearly 600 programming languages for web & mobile application development in the world. Programming languages are growing rapidly to meet the requirements of the latest technologies available in the market.

When choosing the most popular programming languages ​​today or in the future, you should focus on the most developing technology, and the skills needed to achieve your business goals. Here, we have listed some of the most popular programming languages on the basis of various criteria, like popularity, career prospects, open-source, latest trends, etc.


Python is a fast and easy-to-deploy programming language commonly used for building flexible web applications. It is generally recognized as one of the best programming language that can be easily learned. Many popular applications like Instagram, Pinterest, YouTube, SurveyMonkey are developed in Python. 

Python development offers great library support and has a huge developer network. The best part about Python development is that it is considered ideal for developing both iOS and Android apps. The Python programming language is very flexible and easy to read, making it again a widely-used programming language for multi-script applications. 

Python app development also provides multiprocessing and multithreading, which makes the application much better at executing and responding to commands.
