/* # Anagrams

​

An anagram is a word or phrase that is formed by rearranging the letters of another word or phrase, in this challenge using all of the original letters exactly once. Some examples of anagrams are:

​

* `act` = `cat`

* `dog` = `god`

* `angered` = `enraged`

* `a gentleman` = `elegant man`

* `Tom Marvolo Riddle` = `I am Lord Voldemort`

​

## Initial Challenge

​

This challenge builds on the concepts from the Palendrome challenge. Write a function that will accept an array of strings, and print groups of anagrams, ignoring words that don't have a matching anagram.  The snippet below shows an example input, and the expected output:

​

```

Input: ['cat', 'dog', 'bat', 'bar', 'rat', 'rob', 'scram', 'god', 'act', 'crams', 'tar', 'angered', 'enraged', 'marcs']

Output (in any order):

cat, act

dog, god

rat, tar

scram, crams, marcs

angered, enraged

```

​

## Advanced Challenge

​

Non-alphanumeric characters in anagrams can be ignored, such as `Tom Marvolo Riddle` = `I am Lord Voldemort` and `Election results` = `Lies—let's recount`. Does your function work properly with these inputs?

​

```

["Madam, I'm Adam", 'cat', "I'm Adam, Madam", 'scram', 'Election results', 'act', 'Crams', 'Tom Marvolo Riddle', 'marcs', 'rob', 'I am Lord Voldemort', "Lies-let's recount"]

```
