Documentation

The following functions are currently implemented:

• countLetters(sentence): given a string, return an object with the letter (key) and the number of times each appears in the sentence (value)
• countOnly(array, objectWithTestCriteria): given an array, and an object with true/false values tied to keys you want counted, return how many times that key appears in the array
• findKey(obj, callback): Scan through a passed object for the first key that the callback function returns truthy upon.
• findKeyByValue(object, value): search through an object and return the first key that holds the value.
• flatten(array): Flatten nested arrays into a single layer. Works on multiple layers.
• head(array): return the head (0 index) of an array.
• letterPositions(string): given a sentence string, return an object of keys for each letter that contain an array of the indexies where that letter appears in the string.
• map(array, callback): modify a given array based on the properties of the callback function passed.
• middle(array): return an array containing the value(s) at the centre of a given array.
• tail(array): return an array that no longer contains the 0 index.
• takeUntil(array, callback): collect data from an array until the callback provided returns a truthy value; data is returned as an array.
• without(array, valueToRemove): filter out unwanted values from a given array.
