Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): uses eqArrays to check if two arrays are equal and prints messages
• assertEqual(actual, expected): checks if two values are equal
• assertObjectsEqual(actual, expected): uses eqObjects to check if two objects are equal and prints messages
• countLetters(str): returns the count of each letter in a string
• countOnly(allItems, itemsToCount): returns the count of each letter in a string, but only for the letters specified
• eqArrays(arr1, arr2): checks if two arrays are equal
• eqObjects(object1, object2): checks if two objects are equal
• findKey(object, callback): returns the key of a given object, if the key's value satisfies the callback function
• findKeyByValue(object, value): finds a key based on the value passed
• head(arr): returns the head of an array (first element)
• middle(arr): returns the middle of an array (one or two elements)
• tail(arr): returns the tail of an array
• letterPositions(sentence): returns an object where the keys are the letters in a string and the values are the indexes at which those letters appear
• map(array, callback): based on the callback function provided, performs the function on each element of an array and returns a new array
• takeUntil(array, callback): returns all items from a provided array until the callback provided returns a truthy value
