10 Hardest Programming Languages to Learn (& the Easiest Ones)

Learning a programming language can be complex, but some are far more challenging than others. Many beginners mistakenly choose a language with complex syntax, unusual concepts, and steep learning curves. This can lead to a waste of time for that individual.

The difficulty of a language is impacted by syntax, how it interacts with the system, and its memory management. Choosing the wrong language as a beginner can make programming seem overwhelming. On the other hand, experienced developers find certain languages challenging and helpful to develop logic.

However, not all languages are equally difficult. In this blog, we’ll explore the hardest languages to learn and the easiest ones. We’ll dive into the uses of each language leveraged by software development companies. So, let’s get started!

What Makes a Programming Language Hard to Learn?

Some programming languages are more challenging than others due to their syntax complexity or unconventional rules. Beginners often struggle with languages that require a different way of thinking or lack clear documentation. The following factors contribute to the difficulty of learning a programming language.

Complex Syntax

Languages with intricate or inconsistent syntax make learning difficult. For example, languages like C++ have numerous rules and exceptions, making them hard to master. Esoteric languages like Brainfuck use unconventional symbols, making code unreadable. Complex syntax increases the learning curve and debugging difficulty.

Unfamiliar Programming Practices

Different languages follow different reactices, such as functional, procedural, or logic-based programming. Functional languages like Haskell require thinking in terms of pure functions rather than sequential steps. Logic-based languages like Prolog demand reasoning in terms of rules and facts. If a programmer is used to one practice, switching to another can be tough.

Manual Memory Management

Some languages require developers to handle memory allocation and deallocation manually. C and C++ use pointers, which can lead to memory leaks or segmentation faults. Unlike high-level languages that manage memory automatically, low-level languages require careful resource handling. This adds complexity and increases the chances of errors.

Lack of Learning Resources & Community Support

Languages with limited documentation or smaller communities are harder to learn. If there aren’t enough tutorials, books, or online forums, beginners struggle to find solutions. Older or niche languages like INTERCAL or Malbolge have very few learning resources. A strong developer community makes it easier to overcome challenges.

Strict and Unique Rules

Some languages enforce strict rules that require precise coding styles. Haskell, for instance, has a strict type system that demands deep understanding before writing simple programs. In Whitespace, only spaces, tabs, and newlines form the code, making it almost impossible to debug. Unconventional rules make programming less intuitive for beginners.

A programming language becomes difficult when it introduces unfamiliar concepts or strict rules.
