Which Programming Language Should I Use to Learn Data Structures and Algorithms?

One of the most common questions beginners ask is, "Which programming language should I use to learn Data Structures and Algorithms?"

For instance, I work with PHP or JavaScript, but I often hear that implementing data structures is easier with C++. So, should I learn C++ just to implement Data Structures and Algorithms?

The simple answer is No.

Data Structures and Algorithms are not Language-Specific:

First of all, Data Structures and Algorithms are not bound to any specific programming language. You can implement them in any language you are comfortable with.

That said, if you are a university student or someone interested in competitive programming, I would suggest starting with C++ or even Python. Both are commonly used in competitive programming, but if you've already been working with a programming language, you don't need to switch just to learn algorithms.

Why Do We Use Data Structures and Algorithms?

We use Data Structures and Algorithms to make our code scalable—by optimizing time and space complexity. In other words, they help make our code run faster and use memory more efficiently.

Real-World Application Example:

Let's say you learned how to implement an algorithm in C++. However, you currently work with PHP or JavaScript. Now, imagine your client or company tells you, "This feature worked fine when we had 500 users, but now with 50 million users, the code takes 2 minutes to run. We need an algorithm that can do this in 2-3 seconds."

You might remember learning an algorithm that could solve this problem. But would you say, "I learned this in C++, so I can’t implement it in PHP or JavaScript"? Of course not!

Conclusion

If you're already comfortable with a particular language like PHP or JavaScript, stick with it. Focus on understanding the core concepts of Data Structures and Algorithms, and you'll be able to apply them in any language. Switching languages just for this might slow you down.
