+/**
+ * Reverse a string. It's a common interview question, and it's quite simple.
+ * However, if you really want to impress your interviewer, you'd be well-off to understand multiple solutions to the problem.
+ * Rather than using built-in methods like ".reverse()" (which is fine, but you may be asked to neglect using it), 👍
+ * demonstrate your ability to solve it in different ways.
+ *
+ * Here are three solutions to reversing a string in JavaScript.👏
+ *
+ *
+ * Directions
+ * Given a string, return a new string with the reversed order of characters

+// Solution 1:
+
+function reverseStringSolutionOne(str: string) {
+  return str.split("").reverse().join("");
+}
+
+// Solution 2:
+
+function reverseStringSolutionTwo(str: string) {
+  let reversed: string = "";
+  for (let character of str) {
+    reversed = character + reversed;
+  }
+  return reversed;
+}

+// Solution 3:
+
+function reverseStringSolutionThree(str: string) {
+  return str.split("").reduce((rev, char) => char + rev, "");
