Caesars Cipher

One of the simplest and most widely known ciphers is a Caesar cipher, also known as a shift cipher. In a shift cipher the meanings of the letters are shifted by some set amount. A common modern use is the ROT13 cipher, where the values of the letters are shifted by 13 places. Thus 'A' ↔ 'N', 'B' ↔ 'O' and so on. Write a function which takes a ROT13 encoded string as input and returns a decoded string. All letters will be uppercase. Do not transform any non-alphabetic character (i.e. spaces, punctuation), but do pass them on.

Where do I belong

Return the lowest index at which a value (second argument) should be inserted into an array (first argument) once it has been sorted.

Seek and Destroy

Remove all elements from the initial array that are of the same value as these arguments. Filter through Boolean values.

Mutating Words

Return true if the string in the first element of the array contains all of the letters of the string in the second element of the array.

Chunky Monkey

Splitting arrays into specific sized chunks using a while loop to go to the array. In the loop, I slice the array and use the count as the starting point, ending slice with count + the size. This then pushes out into the number of arrays.

Truncating a String

If num <= string, then return the amt of string. Inner else num > string, then slice the string - 3 characters then + "...". Else if the num = str, return the str by itself.

Contact Cards

A Javascript code that loops through contacts returning the specific contact's name and phone number.
