Documentation

The following functions are currently implemented:

• function1(assertArraysEqual): Asserts if the actual and expected arrays are equal.
• function2(assertEqual): Asserts if actual and expected values are equal.
• function3(assertObjectsEqual): Asserts if two objects are equal.
• function4(countLetters): Takes a sentence (as a string) and then returns a count of each of the letters in the sentence.
• function5(countOnly): Takes a given an array and an object and will return an object containing counts of everything that the input object listed.
• function6(eqArrays): Will take in two arrays and declares thy are of equal value.
• function7(eqObjects): Will take in two objects and declares either true or false based on if they are a perfect match.
• function8(findKeyByValue): Will take in and object and a value, to return first key that matches value given. If no key with the given value is found wil return undefined.
• function9(findKeys): Will take in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• function10(head): Will return the first item in the array.
• function11(letterPositions): Will return all the indices (zero-based positions) in the string where each character is found.
• function12(map): Will take in two arguments: an array to map & a callback function. Then will return a new array based on the results of the callback function.
• function13(middle): Will take in an array and return the middle-most element(s) of the given array.
• function14(tail): Will return the "tail" of an array: everything except for the first item (head) of the provided array.
• function15(takeUntil): Will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• function16(without): Will take in a source array and a itemsToRemove array. It returns a new array with only those elements from source that are not present in the itemsToRemove array. Keywords
