Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): Logs a 'pass/fail' message to the console based on a comparison between an expected output and an actual output.
• assertArraysEqual(actual, expected): Logs a 'pass/fail' message to the console based on a comparison between an expected array and an actual array.
• assertObjectsEqual(actual, expected): Logs a 'pass/fail' message to the console based on a comparison between an expected object and an actual object.
• countLetters(string): Counts the instances of each letter in a string and stores the results in an object.
• countOnly(allItems, itemsToCount): Counts only the specified instances of each element in an array.
• eqArrays(array1, array2): Compares between two arrays to see if they are an exact equal match.
• eqObjects(object1, object2): Compares between two objects to see if they are an exact equal match.
• findKey(object, callback): Uses a callback function to find the first key that returns a truthy value.
• findKeyByValue(object, value): Finds the key of an object by matching with a value passed into the function.
• head(array): Returns only the first element of an array.
• tail(array): Returns everything except the first element of an array.
• letterPositions(sentence): Returns an object that contains the indicies of each letter from a sentence.
• map(array, callback): Takes an array and a callback function as arguments, returns a new array with values altered based on the conditions specified in the callback function.
• middle(array): Returns the middle element(s) of an array. If the length of the array is an odd number, it returns 1 middle element. If it's an even number, it returns the two middle elements.
• takeUntil(array, callback): Loops through an array until the first element specified in the callback function is found, then returns every element from the 0th index until the specified element.
• without(source, itemsToRemove): Accepts a source array and an array of items to remove, then returns a new array of only items not included in the itemsToRemove array.
