Documentation

The following functions are currently implemented:

• assertEqual
  Tests for equality between two values of primitive types and prints out a colorful message to inform if the assertion passes or fails.
• assertArraysEqual
  Tests for equality between two arrays and prints out a colorful message to inform if the assertion passes or fails.
• assertObjectsEqual
  Tests for equality between two objects and prints out a colorful message to inform if the assertion passes or fails.
• eqArrays
  Takes in two arrays and returns true or false based on a perfect match.
• eqObjects
  Takes in two objects and returns true or false based on a perfect match.
• countLetters
  Given a string, returns an object containing counts of each of the letters in that string.
• countOnly
  Given an array and an object, returns an object containing counts of everything that an input object listed.
• findKey
  Given an object and a callback function, returns the first key for which the callback returns a truthy value. If no key is found, returns undefined.
• findKeyByValue
  Given an object and a value, returns the first key which contains the given value. Returns undefined if no key with that value is found.
• flatten
  Flattens a nested array into a single-level array.
• head
  Retrieves the first element from an array.
• letterPositions
  Returns all the indices in a string where each character is found.
• map
  Returns a new array based on the results of the callback function on every element of the given array.
• middle
  Retrieves the middle-most element(s) of an array.
• tail
  Retrieves every element except the first element (head) of the array.
• takeUntil
  Returns a slice of the given array with elements taken from the beginning. Elements are taken until the callback returns a truthy value.
• without
