What are the differences between foreach and for loops?

What are the differences between foreach and for loops?

The main difference is that a for loop gives you more control over the iteration process, while foreach is simpler and cleaner for iterating over collections.

Can you give me an example of each?

Sure! In a for loop, you might write: for (int i = 0; i < array.length; i++) { console.log(array[i]); }. In a foreach loop, it would be: array.forEach(item => console.log(item));.

When should I use foreach instead of for?

Use foreach when you want to iterate over all elements in a collection without needing the index. It's cleaner and less error-prone.

Are there any performance differences?

Generally, for loops can be more performant in certain scenarios, especially with large datasets, but the difference is often negligible for most applications.
