Documentation

The following functions are currently implemented:

  • head(...): returns the first item in the array
  • middle(...): take in an array and return the middle-most element(s) of the given array
  • tail(...): returns everything except for the first item (head) of the provided array
  • countOnly(...): given an array and an object, it will return an object containing counts of everything that the input object listed.
  • countLetters(...): return an object where each unique character encountered is a property of the object and the value for that property/key should be the number of occurrences for that character.
  • findKey(...): takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
  • findKeyByValue(...):which takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
  • flatten(...): take in an array of arrays and return a "flattened" version of the array.
  • letterPositions(...): takes in a string and returns an object with unique letters and the index position of the letter occurences.
  • map(...): map function will take in two arguments:An array to map and a callback function. The map function will return a new array based on the results of the callback function.
  • takeUntil(...): this will keep collecting items from a provided array until the callback provided returns a truthy value.
  • without(...): return a subset of a given array, removing unwanted elements
