Documentation

The following functions are currently implemented:

• assertArraysEqual(...): Assert whether two arrays are equal
• assertEqual(...): Assert whether two primitive values are equal
• assertObjectsEqual(...): Assert whether two objects are equal
• countLetters(...): Count the number of times each letter occurs in a given string
• eqArrays(...): Check if two arrays are equal
• eqObjects(...): Check if two objects are equal
• findKey(...): 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(...): Takes in an object and a value. It scans the object and returns the first key which contains the given value.
• flatten(...): Take in an array containing elements including nested arrays of elements, and returns a "flattened" version of the array
• head(...): Returns the first value of an array.
• letterPositions(...): Returns all the indices (zero-based positions) in the string where each character is found.
• map(...): Takes in an array to map and a callback function. Returns a new array based on the results of the callback function.
• middle(...): Returns the middle value of an array.
• tail(...): Returns all but the first value of an array.
• takeUntil(...): Collects items from a provided array until the callback provided returns a truthy value.
• without(...): Returns a subset of a given array, removing unwanted elements.
