-
-Creates a function that accepts a string parameter and output whether its an isogram or not.
-
-- Use `String.toLowerCase()` to convert the string to lowercase letters.
-- Use `String.prototype.split()`, `String.prototype.indexOf()` and `Array.prototype.every()` to split the string into substrings, run a test for all the elements in that array and finally return the index of first occurence of a specified value in a string.
-- Function returns true if the string is an isogram (that is no letter is repeated) else returns false.
-- Returns false if called with no parameter.

-```js
-const isIsogram = (str = null) => {
-  if(str == null) return false;
-  str = str.toLowerCase();
-  return str.split("").every((c, i) => str.indexOf(c) === i);
