without(arr1, arr2): Returns a new array which equals the element of the first - the second. -
takeUntil(arr, val): Iterates through each item of array and pushes them to a new array until it element of the array matches the value. -
assertEqual(actual, expected): Checks strickt equality between two values and console logs the result. -
eqArrays(arr1, arr2): Returns true or false if the arrays match. -
assertArraysEqual(arr1, arr2): Uses eqArrays to log if the arrays match. -
eqObjects(obj1, obj2): Returns true or false if the objects match. -
assertObjectsEqual(arr): Uses eqObjects to log if the objects match. -
findKey(obj, val): Scans 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. -
countOnly(arr, val): Returns how many times the value is found in the array. -
