const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• assertArrayEquals(arr1, arr2): checks if given arr1 is equal to arr2, console logs whether it was a pass or fail.
• assertEqual(actual, expected): checks if actual is equal to expected and console logs whether it was a pass or fail.
• assertObjectEqual(actual, expected): checks if actual object given is equal to expected object and console logs if it was a pass or a fail.
• countLetters(sentence): receives a given sentence and counts the amount of times each letter appears.
• countOnly(allItems, itemsToCount): receives a given object and an item to count and counts the amount of times the item appears in the object.
• eqArrays(arr1, arr2): receives an arr1 and arr2 and checks to see if the arrays are equal.
• eqObjects(object1, object2): receives an object1 and object2 and checks to see if the objects are equal.
• findKeys(object, callback): receives an object and a callback function and returns the key of the matching truth value outputted from the callback function.
• findKeysByValue(obj, value): receives an object and a value and returns the corresponding key from the value.
• head(arr): returns the first element of a given array.
• letterPositions(sentence): returns the index position(s) of a letter from a given sentence.
• map(array, callback): returns an array of the letter at index position when given an array of strings.
• middle(arr): returns the middle index of an array. If the array is even, it will return the middle index and middle index-1.
• tail(arr): returns the length of the resulting array not including the first index.
• takeUntil(array, callback): receives an array and a callback function and returns the array up until the condition of the callback function is satisfied.
• without(source, itemsToRemove): receives a source array and an item to remove from the array and returns the array without the given item input.
