How can I debug variable shadowing in my code?

Variable shadowing occurs when a variable in a local scope has the same name as a variable in an outer scope. To debug it, you can start by checking the variable declarations in your code.

What tools can I use to identify shadowed variables?

You can use linters like ESLint for JavaScript or PyLint for Python, which can help identify shadowed variables.

Can you give me an example of variable shadowing?

Sure! In JavaScript, if you have a variable x in the global scope and then declare let x = 5; inside a function, the function's x shadows the global x.

How can I avoid variable shadowing in my code?

To avoid variable shadowing, use unique variable names, or consider using block scope with let and const to limit the scope of your variables.
