Daily Codewars #26

Question

codewars link (opens new window) In order to stop too much communication from happening, your overlords declare that you are no longer allowed to use certain functionality in your code!

Disallowed functionality:

• Strings
• Numbers
• Regular Expressions
• Functions named "Hello", "World", "HelloWorld" or anything similar.
• Object keys named "Hello", "World", "HelloWorld" or anything similar. Without using the above, output the string "Hello World!" to prove that there is always a way.

String, Numbers, Regex, 그리고 hello world랑 비슷한 문자가 들어가는 function, object key를 쓰지 말고 Hello world!를 출력하는 문제이다.

My Solution

var abc = function() {
  var obj = {
    dlroW:x, olleH:hello}
  var x = new String();
  String.constructor = Object.keys(obj).shift();
  console.log(x.constructor);
  var w1 = Object.keys(obj).shift();
}
var helloWorld = abc;

object의 키값으로 넣고, 그걸 reverse하는 식으로 해볼까 했는데. 계속 걸림돌이 되는 '!'의 문제. 결국 이 문제는 잠시 keep해놓기로... ㅠㅠ 빠가야로
