Have you ever experienced frustration and confusion while coding?

If you need a boost of creativity or assistance in understanding existing code, you might feel that AI tools like ChatGPT have got you covered.

It's crucial to understand the limitations of ChatGPT. While it can be a fantastic aid, it's not infallible. It's important to combine its suggestions with your critical thinking, review, and domain knowledge to ensure the quality and correctness of the code.

Explore the pros, cons, and best practices of using ChatGPT to write code, so you can make the most of this tool while being mindful of its limitations.

My journey of learning to code with ChatGPT

About two months ago, I was excited to start learning to code, even though I didn't know much about it. So, I decided to get help from ChatGPT.

I was surprised by how amazing it was! It could write pieces of code for me, explain how they work, and even give suggestions to make them better. It felt like having my own coding tutor right there with me.

I felt I could be a programmer just by learning code from ChatGPT.

As I dove into using ChatGPT, I relied heavily on its code suggestions. It was exciting to see lines of code magically appear before my eyes, seemingly solving problems effortlessly.

I felt I was making progress and becoming a proficient coder — without testing the code in real contexts.

But one day, I decided to put ChatGPT's generated code to the test. I asked my friend, an experienced programmer, to run the code on a real system.

It didn't work as expected. The code had some critical flaws, and the program crashed. We tried with another code generated by ChatGPT and that worked. I realized that relying solely on ChatGPT's code output was not enough.

This experience made me realize the limitations of ChatGPT as a coding tool. While it can generate code snippets and offer suggestions, it lacks the contextual understanding and project-specific knowledge that a human programmer possesses.

It's like having a language translator who might occasionally miss nuances or cultural references.

Does ChatGPT really know how to code?

I asked ChatGPT: "From where do you grab the information or data when I ask you to write any specific code?"

Here is the answer it gave me:

It's important to note that ChatGPT is a machine-learning model and has its limitations. While it can generate impressive and useful responses, it may occasionally produce inaccurate or nonsensical outputs. It does not possess true understanding or consciousness but relies on patterns in the data it was trained on.

This is why it's essential to review, validate, and test the code generated by ChatGPT using your own critical thinking and expertise.

  • ChatGPT may struggle to understand the specific context, requirements, or constraints of your project.

  • It might not consider the bigger picture or domain-specific considerations, leading to code suggestions that may not align with your goals or produce optimal results.

Incomplete Knowledge and Narrow Training Data

  • ChatGPT's training data includes a vast amount of text from various sources, but it may not cover all programming languages, frameworks, or niche domains.

  • This can result in incomplete or inaccurate code suggestions, especially in less commonly used or specialized areas.

Potential Inaccuracies and Logical Errors

  • While ChatGPT aims to generate syntactically correct code, it's not perfect and can produce code with logical errors.

  • It's important to review and validate the generated code to ensure its correctness and address any potential issues.

Security and Privacy Concerns

  • Sharing sensitive or proprietary code with ChatGPT may pose security risks, as it may not have been trained to handle such confidential information.

  • Be cautious about sharing code that contains sensitive or proprietary data.

How can you use ChatGPT to write code, then?

You can use ChatGPT with your domain knowledge while being aware of its limitations.

Combine ChatGPT with Your Expertise

  • Ues ChatGPT as a complementary tool to leverage its code generation capabilities while incorporating your own domain knowledge and expertise.

  • Consider it as a collaborative aid rather than a substitute for your skills and understanding of the problem.
