What are some common errors when using forEach in JavaScript?

What are some common errors when using forEach in JavaScript?

Some common errors include not returning values, modifying the array while iterating, and using incorrect context.

Can you explain why modifying the array during iteration is a problem?

Modifying the array can lead to unexpected behavior, as the iteration may skip elements or cause infinite loops.

What happens if I don't return a value in forEach?

If you don't return a value, the forEach will simply execute the callback for each element without any output.

Are there alternatives to forEach that handle these issues better?

Yes, alternatives like map, filter, or for...of loops can provide more control and avoid some of these pitfalls.
