Documentation

The following functions are currently implemented:

• assertArrayEqual(Actual, Expected): takes in two arrays and asserts if they are equal or not
• assertEqual(Actual, Expected): takes in two primitive values and asserts if they are equal or not
• assertObjectsEqual(Actual, Expected): takes in two objects and asserts if they are equal or not
• countLetters(String): takes in a string and returns an object with each letter - excluding spaces - as a key and how many time the appear in the string as the key value
• countOnly(AllItems, ItemsToCount): takes in an array of items and an object of items to count. Will return an object with the count values
• eqArrays(Array1, Array2): takes in two arrays and returns true/false if they are equal or not
• eqObjects(Object1, Object2): takes in two objects and returns true/false if they are equal or not
• findKey(Object, Callback): take in an object and a callback function to search for the key. Will return the key name that evaluates the callback to true
• findKeyByValue(Object, Value): takes in an object and a primitive value. Will return the first key that's value matches the input value
• flatten(Array): takes a nested array and returns an unnested version of the input array
• head(Array): returns the first item in an array
• letterPositions(String): takes in a string and returns an object with each a key for each letter excluding space. Each key has an array of every position the letter appeared in the string.
• map(Array, Callback): takes in an array and a callback function. Returns an array of all the values returned by the callback function
• middle(Array): takes in an array and returns the middle value of an array. Returns an array with two values for arrays with an even length
• tail(Array): takes in an Array returns every item after the head of the array
• takeUntil(Array, Callback): takes in an array and a callback function. Returns an array of all items in the input array until the callback evaluates to true
• without(Array, ItemsToRemove): takes in an array and a second array of items to remove. Returns a copy of the first array with all values in the second array removed
