Documentation

The following functions are currently implemented:

• countLetters("sentence", () => {}): counts every letter of a given sentence and returns an object containing that count
• countOnly([array], obj{elem: true, elem1: false, ...}): counts desired elements from an object in an array and returns the counts as an object {key: count, ...}
• findKeyByValue(obj{key: value, ...}, "value"): finds the first key that has the desired value
• findKey(obj{key: value, ...}, callback()): finds the first key that matches the callback function
• flatten([array]): turns a given array to a single-level array
• head([array]): returns the first element of the array
• letterPositions("string"): takes a single string and returns an object {'char': indexes of char, ...}
• map([array], callback()): takes an array and returns an array with the callback function applied to each element of the initial array
• middle([array]): returns the middle element of an array if the array is longer than 3. Returns an empty array if length is less than 2. Even length arrays return a 2 element array
• tail([array]): returns a copy of the array without the first element
• takeUntil([array], callback()): returns an array that has each element of the given array until the callback function is false
• without([baseArray], [removalArray]): removes an element from the removal array from the base array and returns the base array
