Reverse a string

You have been asked to write a function reverseAString(str) that takes in a string str as an argument. The function should return a new string that is the reverse of the input string.

Instructions

• If the input string is empty, then return an empty string.
• The output should always be the argument string in reverse order.

Example test cases

reverseAString("hello") // Output: "olleh"
reverseAString("hi") // Output: "ih"
reverseAString("gfedcba") // Output: "abcdefg"

Hints

• You can chain multiple built-in methods.
• Strings are immutable, so return a new string.
