How do I iterate over an array in Ruby?

You can use methods like each, map, or select to iterate over arrays in Ruby. Which one would you like to know more about?

Can you explain how the each method works?

Sure! The each method allows you to loop through each element of the array. For example: array.each { |element| puts element } will print each element.

What about using map? How is it different?

The map method transforms each element of the array and returns a new array. For instance, array.map { |element| element * 2 } will double each element.

Thanks! Are there any other useful methods for array iteration?

Yes, methods like select, reject, and reduce are also very useful for different types of iterations.
