What are the different ways to iterate over an array in JavaScript?

In JavaScript, you can iterate over an array using several methods: for loop, forEach, map, and for...of.

Can you explain how the forEach method works?

Sure! The forEach method executes a provided function once for each array element. It doesn't return a new array.

What about the map method? How is it different?

The map method also executes a function for each element, but it returns a new array with the results of the function.

Are there any performance differences between these methods?

Yes, performance can vary. Generally, for loops are faster for large arrays, while forEach and map are more readable.
