Documentation

The following functions are currently implemented:

• head: returns the first item in an array.
• tail: returns all items but the first item of an array.
• middle: returns the middle item of an array with an odd number of items and the middle two items for an array with an even number of items.
• assertArraysEqual: asserts whether two arrays are equal.
• assertEqual: asserts whether two items (not array or object) are equal.
• assertObjectsEqual: asserts whether two objects are equal.
• countLetters: counts how many of each letter is in a string.
• countOnly: counts only specified items in an array.
• eqArrays: compares two arrays two determine if they are equal.
• eqObjects: compares two objects two determine if they are equal.
• findKey: takes in an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue: search for a key on an object where its value matches a given value.
• flatten: flattens nested arrays into a single array.
• letterPositions: returns all the indices in the string where each character is found.
• map: creates a new array populated with the results of calling a provided function on every element in the calling array.
• takeUntil: creates slice of the array with elements taken from the beginning until the desired requirement is fulfilled.
• without: filters data to remove unwanted items.
