How do I loop through an array in JavaScript?

You can use a for loop, forEach method, or a for...of loop. Which one would you like to know more about?

Can you explain the forEach method?

Sure! The forEach method executes a provided function once for each array element. Here's an example: array.forEach(element => { console.log(element); });.

What about using a for...of loop?

The for...of loop is great for iterating over iterable objects like arrays. It looks like this: for (const element of array) { console.log(element); }.

Are there any performance differences between these methods?

Yes, for loops are generally faster for large arrays, while forEach and for...of are more readable and easier to use.
