What are some common mistakes when using higher-order functions?

Some common mistakes include misunderstanding how callbacks work, not returning values correctly, and confusing function scope.

Can you explain what a callback is?

A callback is a function passed as an argument to another function, which is then invoked inside that function.

What happens if I forget to return a value in a higher-order function?

If you forget to return a value, the function will return undefined, which can lead to unexpected behavior in your code.

How can I avoid these mistakes?

You can avoid these mistakes by thoroughly testing your functions, using clear naming conventions, and reviewing your code for proper returns.
