Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2) : Console.logs an appropriate message to the console, based on a perfect match.
• assertEqual(actual, expected) : Compares two values, and console.logs an appropriate message to the console, based on a perfect match.
• assertObjectEqual(object1, object2) : Console.logs an appropriate message to the console, based on a perfect match.
• countLetters(string) : Returns a count of each of the letters in the string.
• countOnly(array, object) : Returns an object containing counts of everything that the input object listed.
• eqArrays(array1, array2): Returns true or false based on a perfect match.
• eqObjects(object1, object2) : Returns true or false based on a perfect match.
• findKey(object, callback) : Scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue(object, value) : Scans the object and returns the first key which contains the given value. If no key with that given value is found, then it returns undefined.
• head(array): Returns the first item in an array.
• letterPositions(string) : determines the letters of a given string, and at what positions those letters occur. Returns an object where the letter is a key, and its value is all the indices in the string where each character is found.
• map(array, callback) : Returns a new array after the callback function changes the values of the original array.
• middle(array) : Return the middle-most element(s) of the given array.
• tail(array): Returns the tail of an array (everything except for the first item (head) of the provided array).
• takeUntil(array, callback) : Returns a slice of the array with elements taken from the beginning until the callback returns a truthy.
• without(array, itemsToRemoveArray) : Returns a subset of a given array, removing the unwanted elements included in the itemsToRemoveArray.
