The following functions are currently implemented:

• eqArrays : takes in two arrays and returns a boolean value indicating whether they are equal. click here for example
• assertEqual : compares two values for equality and returns a message indicating whether the assertion passed or failed. click here for example
• assertArraysEqual : compares two arrays for equality and returns a boolean value. click here for example
• assertObjectsEqual : compares two objects for equality and returns a message indicating whether the assertion passed or failed. click here for example
• countLetters : takes in a string and returns an object containing a count of each letter in the string (excluding spaces). click here for example
• countOnly : takes in an array of items and an object containing a set of items to count, and returns an object with counts of the items in the original array that are specified in the input object. click here for example
• eqObjects : takes in two objects and returns a boolean value indicating whether they are equal. click here for example
• findKey : takes in an object and a callback function, and returns the first key for which the callback function returns a truthy value. click here for example
• findKeyByValue : takes in an object and a value, and returns the first key in the object that has the specified value. click here for example
• flatten : takes in an array and returns a new flattened array (an array with all subarrays flattened into a single level). click here for example
• head : takes in an array and returns the first element. click here for example
• letterPositions : takes in a string and returns an object that contains arrays of the positions of each letter in the string. click here for example
• map : takes in an array and a callback function, and returns a new array with each element transformed by the callback function. click here for example
• middle : takes in an array and returns the middle element(s) of the array. click here for example
• tail : takes in an array and returns a new array with all elements except for the first element of the input array. click here for example
• takeUntil : takes in an array and a callback function, and returns a new array that includes all elements of the input array up until the point where the callback function returns a truthy value. click here for example
• without : filters elements from the source array and returns a new array that excludes any elements that are also in the itemsToRemove array. click here for example
