Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Takes in 2 arrays and outputs a message depending on whether they're equal or not.
• assertEqual(actual, expected): Takes in 2 arrays and outputs a message depending on if their equality is true or not.
• assertObjectsEqual(actual, expected): Takes in 2 objects and outputs a message depending on their key/value pairs equality
• countLetters(phrase): Takes in a sentence/phrase and outputs an object containing key/value pairs of each letter's count
• countOnly(allItems, itemsToCount): Takes in an object and array. Returns a count of appropriate object items that are present in array.
• eqArrays(array1, array2: Takes 2 arrays, compares their exact values and returns true or false.
• eqObjects(object1, object2): Takes in 2 objects compares their exact key/values and returns true or false.
• findKey(object, callback): Takes in an object and a callback. Returns the first key in the object that equals true when matched with the callback value.
• findKeyByValue(objToScan, valToFind): Takes in an object and a value. Returns the first key which contains the given value or returns undefined.
• head(array): Takes in an array and returns the first element.
• letterPositions(phrase): Takes in a sentence/phrase and returns an object displaying the indexes of each letter.
• map(array, callback): Takes in an array and callback. Returns another array based on what the callback asks for.
• middle(array): Takes in an array and returns the middle element(s).
• tail(array): Takes in an array and returns another array containing all elements except for the head element.
• takeUntil(array, callback): Takes an array and callback. Returns a subset of the array from the beginning up until a value returns true when matched with the callback.
• without(source, itemsToRemove): Takes in an array and items to remove. Returns a subset of with the indicated items removed.
