How do I iterate through an array in JavaScript?

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

Can you show me an example using forEach?

Sure! Here's an example:

const fruits = ['apple', 'banana', 'cherry'];
fruits.forEach((fruit) => {
  console.log(fruit);
});

What about using a for loop?

Absolutely! Here's how you can do it with a for loop:

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

Are there any other methods I should know about?

Yes, you can also use the map method, which creates a new array with the results of calling a function on every element:

const fruits = ['apple', 'banana', 'cherry'];
const upperFruits = fruits.map(fruit => fruit.toUpperCase());
console.log(upperFruits);
