const _ = require('@primetee/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
head(arr, expectedResult)
: Head function returns the first element in the array.tail(arr, expectedResult)
: Tail function returns a new array with the elements of an array less the first element.middle(arr, expectedResult)
: Middle function returns the middle element if array length is odd or an array of the two middle elements when array length is even.assertArraysEqual(array1, array2)
: Compares two arrays and console logs if they are equal or not.assertEqual(actual, expected)
: Compares two variables and logs an assertion (failed or passed).assertObjectsEqual(actual, expected)
: compares two objectsa and asserts whether they are same or not.countLetters(str)
: counts the number of same letters in a string and return an object with numbers as values and letters as properties.countOnly(allItems, ItemsToCount)
: Return counts for a specific subset of those items.eqArrays(array1, array2)
: Function takes in two arrays and returns true or false, based on a perfect match.eqObjects(Obj1, Obj2)
: Function takes in two objects and returns true or false, based on a perfect match.findKey(OBJ, Callback)
: Function 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.findKeyByValue(Obj, value)
: Function takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.flatten(array)
: Function takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the arraywithout(source, itemToRemove)
: Function will return a subset of a given array, removing unwanted elements.letterPosition(sentence)
: Function will return all the indices (zero-based positions) in the string where each character is found.map(array, callback)
: Function will return a new array based on the results of the callback function. *takeUntil(array, callback)
: Function will return a "slice of the array with elements taken from the beginning
