Documentation
The following functions are currently implemented:
-
head: Retrieve the first element from the array -
tail: Returns the "tail" of an array. Everything except for the first item (head) of the provided array -
middle: Returns the middle-most element(s) of the given array -
countLetters: Takes in a sentence (as a string) and then return a count of each of the letters in that sentence -
countOnly: Returns an object containing counts of everything that the input object listed -
findKey: Returns the first key for which the callback returns a truthy value -
findKeyByValue: Scan an object and return the first key which contains the given value -
letterPositions: Return all the indices (zero-based positions) in the string where each character is found -
map: Returns an array of numbers that should be the length of each array element input -
takeUntil: Returns a slice of the array with elements taken from the beginning. It should keep going until the callback/predicate returns a falsy value -
