Documentation

The following functions are currently implemented:

• countLetters(inputString)): Take in a string, count how many of each character in the string there are.
• countOnly(allItems, itemsToCount): Take an array of strings and an object specifying what to count within the array.
• eqArrays(arrayOne, arrayTwo): Compare each element of the two arrays in order and return true if the two arrays are the same.
• eqObjects(object1, object2): Return true if two objects have identical keys with identical values.
• findKey(object, callback): Take in an object and a callback; scan the object and return the first key for which the callback returns a truthy value.
• findKeyByValue(list, find): Take in an object and a value; scan the object and returnt he first key which contains the given value. If not found, return undefined.
• head(data): Take in an array and return the first element of the array.
• letterPositions(sentence): Take a string (sentence) and return all the indices in the string where each character is found.
• map(array, callback): Take in an array and a callback; return a new array based on the results of the callback function.
• middle(array): Take in an array and return an array with only the middle element(s).
• tail(data): Take in an array and return an array without the first element of the array.
• takeUnit(array, callback): Take in an array and a callback; return a "slice of the array with elements taken from the beginning" until the callback returns a truthy value. Callback should only be provided one value.
