const _ = require('@sasu.osayande/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
const assertArraysEqual = function(array1, array2)
: used in conjunction with eqArrays to evaluate two arrays.const assertEqual = function(actual, expected)
: implemented our own assert function.const assertObjectsEqual = function(actual, expected)
: assertion to help us test functions that return objects.const countLetters = function (sentence)
: used to return a count of letters in a given string.const countOnly = function(allItems, itemsToCount)
: used to return an object containing counts of the input object from an array.const eqArrays = function(array1, array2)
: used to compare two arrays.const eqObjects = function(object1, object2)
: used to compare two objects.const findKey = function(object, callback)
: used to return the first key for which a callback function returns a truthy value.const findKeyByValue = function(object, value)
: used to return a key by inputing the value of that key.const head = function(first)
: retrieves the first element in an array.const letterPositions = function(sentence)
: used to return an array of indices of a character in a string.const map = function(mapArray, callbackFn)
: implemented our own version of map().const middle = function(array)
: retrieves the middle-most elements of a given array.const tail = function(minusHead)
: returns a new array without the first element ("head") of the original array.const takeUntil = function(array, callback)
: returns a slice of an array, stopping/excluding the element equal to the callback fn.const without = function(source, itemsToRemove)
: removes elements from the first array that are found in the second array.
