const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
assertArraysEqual(array1, array2)
: Console.logs an appropriate message to the console, based on a perfect match.assertEqual(actual, expected)
: Compares two values, and console.logs an appropriate message to the console, based on a perfect match.assertObjectEqual(object1, object2)
: Console.logs an appropriate message to the console, based on a perfect match.countLetters(string)
: Returns a count of each of the letters in the string.countOnly(array, object)
: Returns an object containing counts of everything that the input object listed.eqArrays(array1, array2)
: Returns true or false based on a perfect match.eqObjects(object1, object2)
: Returns true or false based on a perfect match.findKey(object, callback)
: Scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.findKeyByValue(object, value)
: Scans the object and returns the first key which contains the given value. If no key with that given value is found, then it returns undefined.head(array)
: Returns the first item in an array.letterPositions(string)
: determines the letters of a given string, and at what positions those letters occur. Returns an object where the letter is a key, and its value is all the indices in the string where each character is found.map(array, callback)
: Returns a new array after the callback function changes the values of the original array.middle(array)
: Return the middle-most element(s) of the given array.tail(array)
: Returns the tail of an array (everything except for the first item (head) of the provided array).takeUntil(array, callback)
: Returns a slice of the array with elements taken from the beginning until the callback returns a truthy.without(array, itemsToRemoveArray)
: Returns a subset of a given array, removing the unwanted elements included in the itemsToRemoveArray.
