What is the difference between for and foreach loops?

Can you explain the difference between for and foreach loops?

Sure! A 'for' loop is used for iterating over a range of values, while a 'foreach' loop is specifically for iterating over collections like arrays or lists.

When would I use a foreach loop instead of a for loop?

You'd use a foreach loop when you want to simplify your code and avoid dealing with index values, especially when working with collections.

Are there any performance differences between the two?

Yes, in some cases, a for loop can be more performant, especially if you need to manipulate indices. However, foreach is often more readable.

Can you give me an example of both?

Absolutely! In JavaScript, a for loop looks like this: for (let i = 0; i < arr.length; i++) { console.log(arr[i]); } and a foreach loop would be: arr.forEach(item => console.log(item));.
