+What is an anagram? Well, two words are anagrams of each other if they both contain the same letters. For example:
+
+```js
+'abba' & 'baab' == true
+
+'abba' & 'bbaa' == true
+
+'abba' & 'abbba' == false
+
+'abba' & 'abca' == false
+```
+
+Write a function that will find all the anagrams of a word from a list. You will be given two inputs a word and an array with words. You should return an array of all the anagrams or an empty array if there are none. For example:
+
+```js
+anagrams('abba', ['aabb', 'abcd', 'bbaa', 'dada']) => ['aabb', 'bbaa']
+
+anagrams('racer', ['crazer', 'carer', 'racar', 'caers', 'racer']) => ['carer', 'racer']
+
+anagrams('laser', ['lazing', 'lazy',  'lacer']) => []

+A pangram is a sentence that contains every single letter of the alphabet at least once. For example, the sentence "The quick brown fox jumps over the lazy dog" is a pangram, because it uses the letters A-Z at least once (case is irrelevant).
+
+Given a string, detect whether or not it is a pangram. Return True if it is, False if not. Ignore numbers and punctuation.

+Define a function that takes an integer argument and returns logical value `true` or `false` depending on if the integer is a prime.
+
+Per Wikipedia, a prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.
+Example
+
+```js
+is_prime(1)  /* false */
+is_prime(2)  /* true  */
+is_prime(-1) /* false */
+```
+
+Assumptions
+
+- You can assume you will be given an integer input.
+- You can not assume that the integer will be only positive. You may be given negative numbers as well (or `0`).
+- There are no fancy optimizations required, but still the most trivial solutions might time out. Try to find a solution which does not loop all the way up to `n`.
