Documentation

The following functions are currently implemented:

• countLetters: accepts a string and returns an object with key value pairs to denote each characterin the string, and the number of times it occurred in the string
• countOnly: accepts an array of strings and return counts for a specific subset of those strings (the subset is identified by an object)
• eqArrays: accepts two arrays and returns true or false based on if they are equal
• eqObjects: accepts two objects and returns true or false based on if they are equal
• findKey: accepts an object and a callback function: scans the object and returns the first key for which the callback function returns a truthy value
• findKeyByValue: accepts an object and a value: scans the object and returns the first key which contains the given value
• flatten: accepts an array where some elements may also be arrays and returns a single array with no inner arrays (a "flattened" version of the input array)
• head: accepts an array and returns the first element
• map: accepts an array and a function, and creates a new array with the results of calling the provided function on each element in the input array
• middle: accepts an array and returns the middle element or elements as an array
• tail: accepts an array and returns the same array, but with the first element removed
• takeUntil: accepts an array and a callback function and runs each array element through the function, returning an array with all the items from the original array until the callback provided returns a truthy value
• without: accepts a source array and an array of items to remove, and returns a subject of the source array, removing any elements that were included in the inputted array of items to remove
