I'm looking to enhance my debugging skills and move away from my current method of quickly Googling error messages. My usual process is to panic when something goes wrong, search for the error online, copy and paste a solution, and just hope it works. I want to develop habits that will help me better understand the issues in my code before I start searching for answers. Any practical debugging techniques or suggestions that have worked for you?

Start by thoroughly reading the error message and checking the call stack. Then, navigate to the line of code where the error occurs. Analyze the code to understand the meaning of the error. It's crucial to determine if the error is reproducible since that makes debugging easier. If it is, set breakpoints to capture local values at the moment the error triggers to find the root cause.
A good strategy is to add print statements throughout your code, marking the start and end of key processes, along with error catching. This will help you track where your program might be failing before you consider searching online.
One effective method is to step through your code using a debugger and set breakpoints. This allows you to see how the data changes at each step. If you can't use a debugger, make use of logging statements to track what’s happening in your code. Once you understand the data flow, you can go ahead and Google for solutions if necessary.
Being proficient in your programming language is essential. If you're confused by error messages, it might reflect a lack of fluency in the language itself, rather than an issue with the code. So, maybe focus on enhancing your foundational knowledge and coding practices.
The first step in debugging is understanding the error message you're getting. Most programming languages give pretty decent messages. After, it's about checking your program clauses and making sure you know what the data is supposed to do. If you can’t wrap your head around the error, that’s when you might want to start Googling it.
