How can I debug dynamically typed languages effectively?

What are some effective strategies for debugging dynamically typed languages?

Debugging dynamically typed languages can be challenging. Here are a few strategies you can use: 1. Use print statements to track variable values. 2. Leverage built-in debugging tools like pdb for Python. 3. Write unit tests to catch errors early. 4. Use type hinting where possible to clarify expected types.

How can I use print statements effectively?

When using print statements, make sure to include context in your messages. For example, instead of just printing a variable, you could print its name and value like this: print('Value of x:', x). This helps you understand the flow of your program better.

What built-in debugging tools should I consider?

For Python, you can use pdb, which allows you to set breakpoints and step through your code. For JavaScript, the browser's developer tools provide a powerful debugger. Each language has its own set of tools, so it's worth exploring the documentation.

Are there any common pitfalls to avoid?

Yes, common pitfalls include assuming variable types, not checking for null or undefined values, and neglecting to test edge cases. Always validate your inputs and outputs to avoid unexpected behavior.
