Chapter 5 - Arrays and Blocks
Exercise 1: Converting a String to an Array and back
We have a string that’s supposed to contain a list of fruit, separated by commas. But there are some items in there that shouldn’t be. Write a script that does the following:
- Use the
split
method with an argument of", "
to split the string into an array. - Use the
pop
method to discard the last array element. - Use the
shift
method to discard the first array element. - Use the
join
method with an argument of", "
to join the array back into a string, and print the result.
