join an array of characters into a string in ruby

To join an array of characters into a string in Ruby, you can use the .join method. Here's an example:

main.rb
array_of_chars = ['H', 'e', 'l', 'l', 'o']
string = array_of_chars.join('')
puts string #=> "Hello"
100 chars
4 lines

In the example above, we first define an array of characters called array_of_chars. We then call the .join method on this array with an empty string as the separator. The .join method concatenates all elements of the array into a single string, with the separator string between each element. Since we're using an empty string as the separator, the resulting string contains no separator characters and consists only of the characters in the original array. Finally, we print the resulting string to the console using puts.
