When should I use loops in JavaScript?

When should I use loops in JavaScript?

You should use loops in JavaScript when you need to execute a block of code multiple times, especially when dealing with arrays or collections.

Can you give me an example of a loop in JavaScript?

Sure! Here's a simple example using a for loop to iterate through an array:

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

What are the different types of loops in JavaScript?

JavaScript has several types of loops: for, while, do...while, and forEach. Each has its own use cases.

When should I use a forEach loop instead of a for loop?

Use forEach when you want to iterate over an array without needing the index, as it provides a cleaner syntax.
