Isogram with “word”

Question

JavaScript

Create a funtion called isIsogram that takes one argument, a word to test if it's an isogram. This function should return a boolean indicating whether it is an isogram (true) or not (false).

Example:

isIsogram("Dermatoglyphics")
Expected result:

true

Answer 1

So if you want to know if word A is an isogram of word B,
List out all the letters of A, then if you see the same letter in B, delete those 2 identical letters. Remember to preserve duplicates.

There's part of the algorithm. Now code!

Answer 2

Not too sure how to say it in JS but in Python,

def is_isogram(word):
return len(word) == len(set(word))
