When should I use a forEach loop instead of a for loop?

Can you explain when to use a forEach loop instead of a for loop?

Sure! Use a forEach loop when you want to iterate over an array without needing the index, and when you don't need to break out of the loop.

What are the performance differences between forEach and for loop?

Generally, for loops can be faster than forEach, especially for large arrays, because forEach has some overhead due to function calls.

Are there any situations where a for loop is definitely better?

Yes, if you need to modify the array while iterating or if you need to break out of the loop early, a for loop is better.

Can you give me an example of both?

Of course! ForEach example: array.forEach(item => console.log(item)); For loop example: for(let i = 0; i < array.length; i++) { console.log(array[i]); }.
