add element to ruby array return new array

You can easily add two arrays in Ruby with plus operator. So, just make an array out of your element.

arr = [1, 2]puts arr + [3]# => [1, 2, 3]puts arr# => [1, 2]

ruby arrays copy new-operator

it also works by extending arr using * operator

arr = [1,2]puts [*arr, 3]=> [1, 2, 3]
