Documentation

The following functions are currently implemented:

• assertArraysEqual: Asserts whether two arrays are equal.
• assertEqual: Asserts whether two values are equal.
• assertObjectsEqual: Asserts whether two objects are equal.
• countLetters: A function that receives a string and returns a count of each of the letters in that sentence.
• countOnly: A function that is given an array and an object. It will return an object containing counts of everything that the input object listed.
• eqArrays: A function that takes in two arrays and returns true or false, based on a perfect match.
• eqObjects: A function that takes in two objects and returns true or false, based on a perfect match.
• findKey: A function that takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue: A function that takes in an object and a value. It scans the object and returns the first key which contains the given value.
• flatten: A function that takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• head: A function that returns the first item in an array.
• letterPositions: A function that returns all the indices in the string where each character is found.
• map: A function that will return a new array based on the results of the callback function.
• middle: A function that takes in an array and returns the middle-most element(s) of the given array.
• tail: A function that returns the "tail" of an array: everything except for the first item (head) of the provided array.
• takeUntil: A function that will return a slice of the array with elements taken from the beginning. It should keep going until the callback returns a truthy value.
• without: A function that returns a subset of a given array, removing unwanted elements.
