Most common programming language used in 2022

As a custom software development firm, this is one of the most common questions we are asked. Choosing the best programming language, library or technology stack is essential to successful software development, regardless of the problem you are trying to solve. In this article I will explain the most common criteria used to select the programming language, and list the 5 most common languages used in our experience.

How to select the most adequate programming language?

One of the biggest decisions that a software development team must do before starting a new project, is the selection of the programming language to be used. There are several factors Deproinf’s project managers consider to select the programming language for a new project. Below are some of them.

Type of application
The language to be used highly depends on the type of application you will be developing. For example, building a native Android app traditionally requires knowledge of Java; building a native iOS app requires a Swift or Objective-C skill set, whereas knowledge of C or C++ is critical if you are working with embedded firmware. However there are more recent platforms that are gaining ground over the traditional ones, like React for building composable and reusable user interfaces, or Angular for building single-page client applications using HTML and Type Script.

Project Complexity
The size and complexity of a project play an important role in deciding on what programming language to use. Small projects such as simple marketing sites and simple web application forms to collect data can be done with platforms that require knowledge of PHP, C# or Angular. Medium-sized projects, such as an e-commerce site, call for a more general programming language such as Java or C#. We typically break down complex applications into smaller components.

Company experience
Most software development companies specialize in specific languages and platforms. So, when the time comes to select a language or platform, the tendency is to pick the tools they have more knowledge of. The introduction of a new language implies learning time that might affect the development time and product quality.

Scalability and performance
Scalability is more about a technology stack, which in turn determines the programming languages, rather than the programming language itself. Some battle-tested and popular stacks that have proven to be capable of such scalability include .NET, LAMP, Ruby on Rails (RoR), MEAN and Java Spring.

Seguridad
Every application has different requirements in terms of security. Some languages are more robust than others. Take into consideration the security requirements at the moment of selecting the programming language.
