+####Description:
+
+Write a function makePalindrome that takes a string as the argument and then returns the shortest possible palindrome made from that string without modifying the original string.
+If more than one palindrome can be made, the function should return the solution where the given string appears at the beginning of the palindrome.
+
+Only single word strings will be passed as arguments to the function.
+
+####Example:
+
+```js
+makePalindrome('a') --> 'a'
+makePalindrome('ab') --> 'aba'
+makePalindrome('abc') --> 'abcba'
+makePalindrome('race') --> 'racecar'
+makePalindrome('leveled') --> 'deleveled'
+```
