convert an array to a string in Ruby

  my_array = ["Hello", "World"]
  my_array.join(" ")

This code will convert an array into a string. First, we declared a variable called “my_array” and assigned it an array of two strings, “Hello” and “World”. Then, we invoke the “.join” method on the “my_array” variable. The “.join” method takes one argument, the string which we want to use to separate the individual strings stored in the array. In this case, we are using an empty string (” ”) so that the resulting string doesn’t have any separator. The result of the code will be a string “Hello World”.
