Call it:

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

Documentation

The following functions are currently implemented:

eqArray(arr1, arr2): checks if two arrays are equal, returns true or false eqObjects(obj1, obj2): checks if two objects are equal, returns true or false assertEqual(actual, expected): checks if two inputs are equal, returns true or false

• assertArraysEqual(actual, expected): checks output of eqArrays vs expected, returns assertion assertObjectsEqual(obj1, obj2): checks output of eqObjects vs expected, returns assertion head(arr): returns only the 0 indexed element in an array tail(arr): returns all elements except 0 indexed element in a separate new array middle(arr): returns middle element(s) from an array countLetters(inputString, checkLettersArr): counts how many times a character appears in a string, returns object storing property countOnly(allItemsArr, itemsToCount): takes two arrays, counts elements in one array based on elements given in second array findKeyByValue(obj, value): takes object and value and returns key name for the value findKey(obj, callback ): takes an object and callback, returns the first key for which callback returns truthy value. If no key is found, returns undefined flatten(arr): Takes an array with arrays in it, and returns all elements in all letterPositions(str): Returns the index of all characters in a string matching an input character map(arr, callback): Takes array and calls callback function argument on each element, returns results in new array takeUntil(arr, callback): Takes array and callback, will return new array of elements up until callback function returns true without(arr, itemsToRemove): Takes array and array of items to removes, returns array with items that matched removed
