Documentation

The following functions are currently implemented:

• assertArraysEqual: Asserts whether two arrays are equal

• assertEqual: Asserts whether two primitive values are equal

• asserObjectEqual: Asserts whether two objects are equal

• countLetters: Takes in a sentence (as a string) and then return a count of each of the letters in that sentence

• countOnly: Takes in a collection of items and return counts for a specific subset of those items

• eqArrays: Compares two arrays to check if they are equal to each other

• eqObjects: Compares two objects to check if they are equal to each other

• findKey: Takes an object and a callback and returns the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.

• findKeyByValue: Takes an object and a value and returns the first key which contains the given value. If no key with that given value is found, it returns undefined.

• head: Returns the first item in the array

• letterPositions: Returns all the indices (zero-based positions) in the string where each character is found.

• map: Returns a new array based on the results of the callback function

• middle: Returns an array with only the middle element(s) of the provided array

• tail: Returns the "tail" end of an array, only not including the head

• takeUntil: Returns a "slice of the array with elements taken from the beginning." It should keep going until the callback returns a truthy value

• without: Takes in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove array
