Documentation

The following functions are currently implemented:

• head: A function which returns the first item in the array.
• tail: A function which returns everything except for the first item in the array.
• middle: A function which will take in an array and return the middle-most element(s) of the given array.
• countLetters: A function which will be given an string and an object. It will return an object containing counts of each character that the input object listed.
• countOnly: A function which will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• findKey: A function which takes in an object and a callback. It should will the object and return the first key for which the callback returns a truthy value. If no key is found, then it will return undefined.
• findKeyByValue: A function which takes in an object and a value. It scans the object and returns the first key which contains the given value. If no key with the given value is found, it will return undefined.
• flatten: A function which will take in an array of arrays and return a "flattened" version of the array.
• letterPositions: A function which will return all the indices (zero-based positions) in the string where each character is found.
• map: A function which will take in two arguments: An array to map & A callback function. The map function will return a new array based on the results of the callback function.
• takeUntil: A function which will take in two parameters: An array & a predicate. The function will return a "slice of the array with elements taken from the beginning." It will continue until the predicate returns a truthy value. The predicate should only be provided one value: The item in the array.
• without: A function which will return a subset of a given array, removing unwanted elements.
