Documentation

The following functions are currently implemented:

• assertArraysEqual: Takes in two array arguments and prints a true or false message based on a perfectmatch
• assertEqual: Takes in two string arguments and returns true or false based on a perfect match.
• eqArrays: Takes in two array arguments and prints a true or false based on a perfect match.
• head: Identifies the head of the array.
• middle: Identifies the middle element(s) in an array.
• tail: Removes the first element of an array, then counts the length of the array.
• assertObjectEqual: Takes in two objects arguments and console.log a true or false message based on a perfect match.
• countOnly: Take in a collection of items and return counts for a specific subset of those items.
• countLetters: Takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• eqObjects: Takes in two objects and returns true or false, based on a perfect match.
• findKey: Takes in an object and a callback, scans the object and returns the first keyfor which the callback returns a truthy value. If no key is found, it will return undefined.
• findKeyByValue: Takes in an object and a value, scans the object and returns the first key which contains a given value. If no key with that given value is found, it will return undefined.
• flatten: Takes in an array containing elements including nested arrays of elements, and return a one array of the previously nested arrays.
• letterPositions: Takes in a string and returns and object with an array of index positions for each letter in the string, spaces are skipped.
• map: Takes in an array and a callback function and returns a new array based on the results of the callback function.
• takeUntil: Takes in an array and a callback and returns a slice of the array with elements taken from the beginning until the callback returns a truthy value.
• without: Takes in a source array and an item to remove array and returns a new array with only those elemetns from the source that are not present in the items to remove array.
