Reverse a String

Problem

Reverse the provided string.

You may need to turn the string into an array before you can reverse it.

Your result must be a string.

Remember to use Read-Search-Ask if you get stuck. Write your own code.

Here are some helpful links:

• Global String Object
• String.prototype.split()
• Array.prototype.reverse()
• Array.prototype.join()

Solution

function reverseString(str) {
  var arr = str.split("");
  arr = arr.reverse();
  str = arr.join("");
  return str;
}

reverseString("hello");

Tests

• reverseString("hello") should return a string.
• reverseString("hello") should become "olleh".
• reverseString("Howdy") should become "ydwoH".
• reverseString("Greetings from Earth") should return "htraE morf sgniteerG".
