What are some common mistakes to avoid in Ruby programming?

Some common mistakes in Ruby include using the wrong variable scope, forgetting to use 'end' for blocks, and misusing symbols.

Can you explain the variable scope issue?

Sure! In Ruby, variable scope determines where a variable can be accessed. Using local variables outside their defined scope can lead to errors.

What about the 'end' keyword?

For blocks, methods, and classes, forgetting to include 'end' can cause syntax errors. Always ensure every block has a matching 'end'.

Are there any other common pitfalls?

Yes, another common pitfall is confusing 'nil' with false. In Ruby, 'nil' is not the same as false, which can lead to unexpected behavior.
