How do I loop through an array in JavaScript?

You can use several methods to loop through an array in JavaScript, such as for loops, forEach, and map.

Can you show me an example using a for loop?

Sure! Here's a simple example:

const fruits = ['apple', 'banana', 'cherry'];
for (let i = 0; i < fruits.length; i++) {
    console.log(fruits[i]);
}

What about using forEach?

Using forEach is quite straightforward. Here's how you can do it:

fruits.forEach(fruit => {
    console.log(fruit);
});

Are there any performance differences between these methods?

Yes, there can be performance differences. For loops are generally faster for large arrays, while forEach is more readable and easier to use for smaller arrays.
