• Don’t comment out big chunks of code; use version control instead.

Naming Conventions to Follow

Naming rules are important for code to be easy to read. Using clear and consistent names for things helps a lot.

Some good naming rules include:

Convention	Description	Example
Camel Case	First letter small, rest of words capitalized.	myVariableName
Pascal Case	First letter of each word capitalized.	MyClassName
Underscore Notation	Words split by underscore.	my_variable_name

By using these rules, our code works well and is easy to keep up with.

Debugging Techniques every Coder Should Master

Debugging is key for coders. It’s as important as writing code. With the right methods, debugging can teach you a lot.

Understanding Common Errors

First, learn about common errors. There are syntax, runtime, and logical errors. Syntax errors break the language rules. Runtime errors pop up during use. Logical errors make your program wrong.

Common error types include:

• Syntax errors: Missing semicolons or mismatched brackets.
• Runtime errors: Division by zero or out-of-range values.
• Logical errors: Incorrect algorithm implementation.
