• assertEqual(...): tests assertion that two values are equal, and logs a pass or fail message to the console
• assertObjectsEqual(...): tests assertion that two objects are equal, and logs a pass or fail message to the console
• countLetters(...): receives a string and returns a count the number of letters in that string
• countOnly(...): receives an array and object, then returns an object containing counts of everything listed in the argument object
• eqArrays(...): compares two arrays for strict equality, returning a boolean result
• eqObjects(...): compares two objects for strict equality, returning a boolean result
• findKey(...): takes in an object and a callback, scans the object, then returns the first key for which the callback returns a truthy value
• findKeyByValue(...): receives an object and a value, then returns the first object key whose value contains the given value
• head(...): returns the first item in an array
• letterPositions(...): receives a string, then returns an object of arrays of each unique letter and all the indeces at which they are located in the string
• map(...): receives an array and a callback function, then returns a new array based on the result of the callback on the input array's elements
• middle(...): returns the middle-most element(s) of the given array
