MATLAB is a high-level language designed for numerical computing, widely used in academia and industry. Known for data visualization and complex math functions, MATLAB is essential in engineering and scientific fields.
Major Applications of MATLAB
Data Analysis
Common in fields requiring heavy data manipulation and visualization.
Simulations
Widely used for modeling and simulating engineering systems.
Research
Employed in scientific research for algorithm development.
Why MATLAB is Challenging
Complex Mathematical Syntax
Requires knowledge of mathematical and engineering concepts.
High-Level Functions
Many functions are tailored to scientific applications, which can be difficult to understand without domain knowledge.
10. C: Foundation of Systems Programming
C is a low-level language known for its efficiency and close-to-hardware operations. With strict syntax and manual memory management, C is powerful but challenging to master.
Major Applications of C
Operating Systems
The backbone of many OSes, including parts of Windows and Linux.
Embedded Systems
Used in programming hardware for real-time performance.
Systems Programming
Essential in fields needing direct hardware manipulation.
Why C is Challenging
Strict Syntax and Memory Management
Requires careful memory handling to avoid errors.
Close to Hardware
Offers low-level access, which can be challenging for new programmers.
3 Ways To Know Which Programming Language You Should Use
So, how can you be sure of which programming language would fit your needs the best? Here are 3 ways that can help:
1. Evaluate Your Project Needs
Understanding your goals can guide your choice. For instance, if you’re developing a mobile app, Swift or Kotlin is ideal, whereas Python or R might be better for data science projects.
Tailoring your language choice to your project helps avoid jumping into the most complicated coding language for a simpler task.
2. Assess Learning Curves
Beginners may benefit from starting with an easier programming language like Python or JavaScript before tackling the hardest programming languages to learn, such as Rust or Assembly.
Knowing which type of software is considered the most difficult to learn can help you choose a manageable entry point in programming languages from easiest to hardest.
3. Hire a Professional
If your project is complex or requires advanced expertise, outsourcing web development services to professionals is the best way to go! Doing so would ensure that you get expert guidance that helps you choose the best programming language for your project.

Easiest Programming Language with the Highest Demand
Python is currently one of the easiest programming languages with the highest demand. It’s used by over 51% of developers worldwide, making it an excellent choice for beginners. Its syntax is clear and readable, which has contributed to its immense popularity.
Python ranks as one of the most-used and in-demand languages worldwide, driven by its versatility across fields like data science, web development, and artificial intelligence.
Companies rely heavily on Python, further amplifying its appeal to both new and experienced developers.
What’s the Best Programming Language to Learn?
Choosing the best programming language to learn depends on your goals. For most, the best programming language is hands down JavaScript.
For beginners, Python is often the easiest to pick up due to its readability and community support. However, JavaScript consistently ranks as the most widely used language, with over 65% of developers reporting regular use for web development.
If you’re interested in mobile development, Swift and Kotlin are better suited. Data science enthusiasts often start with Python or R, while web developers rely heavily on JavaScript.
The answer to what’s the hardest programming language may be C++, but tackling it can be rewarding for system-level programming. Each language offers unique advantages and challenges, so the best choice aligns with your career goals and project needs.
Final Verdict
With so many programming languages to consider, the decision depends on your project’s goals and the ‘level’ of challenge you’re prepared to tackle. For beginners, languages like Python or JavaScript make an ideal start, offering simplicity and versatility without steep learning curves.
On the other hand, experienced programmers seeking more control over system processes may find value in the hardest programming languages like Rust or Assembly, known for their powerful optimization capabilities. Whether you’re drawn to ease or complexity, there’s a language to match your tech ambitions.
