ruby on rails array contains multiple values

Start by declaring an array variable in Ruby using the syntax array_name = []. For example, my_array = [] creates an empty array called my_array.
To add values to the array, use the push method. For example, my_array.push("value1") adds the string "value1" to the end of the array.
You can also directly assign values to specific indexes of the array. For example, my_array[0] = "value2" assigns the string "value2" to the first index of the array.
To access the values in the array, use the index number. For example, my_array[0] returns the value at the first index of the array.
To retrieve the total number of elements in the array, use the length method. For example, my_array.length returns the number of elements in the array.
To iterate over all the elements in the array, use a loop such as the each method. For example, my_array.each do |value| allows you to perform an action on each element in the array.
You can also check if an array contains a specific value using the include? method. For example, my_array.include?("value1") returns a boolean value indicating whether the array contains the string "value1".
To remove elements from the array, you can use methods like pop to remove the last element, or delete_at to remove an element at a specific index. For example, my_array.pop removes the last element from the array.
Lastly, you can sort the elements in the array using the sort method. For example, my_array.sort arranges the elements in ascending order.

These are some of the basic operations you can perform on a Ruby array. Remember to adapt these steps to your specific use case and modify the variable and method names accordingly.
