How can I improve the readability of my JavaScript loops?

To improve readability, consider using descriptive variable names, breaking complex loops into functions, and using modern syntax like forEach.

Can you give me an example of a readable loop?

Sure! Instead of using a traditional for loop, you can use array.forEach() like this:

const numbers = [1, 2, 3];
numbers.forEach(num => {
    console.log(num);
});

What about using map instead of forEach?

Using map is great for transforming arrays. It returns a new array based on the results of the function you provide. Here's an example:

const doubled = numbers.map(num => num * 2);
console.log(doubled);

Are there any performance considerations I should be aware of?

Yes, while readability is important, be mindful that methods like forEach and map can be less performant than traditional loops for large datasets. Always profile your code if performance is critical.
