The 15 Best Programming Languages to Learn in 2025

If you’re new to the field of software development, the toughest part of learning programming is deciding where to begin. There are hundreds of programming languages in widespread use, each with its own complexities and idiosyncrasies.

The good news is that as you begin your journey as a software developer, you’ll start to discover the best coding language to learn based on your interests and career goals.

In this article, we’ll go over the most in-demand programming languages as well as how to learn them to kickstart a coding career.

What is a Programming Language?

A programming language is a set of instructions, written in a specific syntax, which tell a computer what tasks to perform and how to perform them. By mastering a programming language, you can create software applications, websites, and other digital tools that shape our world.

Major Types of Programming Languages

In your search for the best programming languages to learn, know that there are multiple types of programming languages—each with its own strengths and limitations.

Here are the major types of programming languages:

1. Procedural Programming Languages: These languages focus on breaking down problems into step-by-step procedures. C, Cobol, BASIC, and Pascal are popular examples.

2. Functional Programming Languages: These languages emphasize manipulating data structures without modifying existing data to promote a more predictable outcome. Haskell and Scala are some well-known functional languages.

3. Object-Oriented Programming Languages: In these languages, programs are organized around objects that contain data (properties) and actions (methods). This object-based approach is widely used, with Python, Java, and C++ being prominent examples.

4. Scripting and Dynamic Languages: These lightweight languages are often used for automating tasks or adding interactivity to web pages. JavaScript and Ruby are commonly used scripting languages.

5. Logic Programming Languages: These languages focus on problem solving through logic and reasoning. They provide a unique way to approach problems and are often used in artificial intelligence applications. Prolog is a notable example of a logic programming language.
