const _ = require('@shamayal/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(firstArray, secondArray)
: an assert function that compares two arrays and logs a message to the console to tell us if they are a match or not -
assertEqual(firstArray, secondArray)
: an assert function that compares two values and logs a message to the console to tell us if they are a match or not -
assertObjectsEqual(object1, object2)
: an assert function that compares two objects and logs a message to the console to tell us if they are a match or not -
countLetters(sentence)
: returns an objects with the count of each of the letters in a sentence -
countOnly(allItems, itemsToCount)
: returns an object containing counts of everything from an array that the input object listed -
eqArrays(firstArray, secondArray)
: takes in two arrays and returns true or false, based on a perfect match -
eqObjects(object1, object2)
: takes in two objects and returns true or false, based on a perfect match -
findKey(objectToScan, callback)
: returns the first key in an object for which the callback returns a truthy value -
findKeyByValue(objectToSearch, valueToFind)
: takes in an object and a value and returns the first key which contains the given value -
head(arrayElements)
: retrieves the first element of an array -
letterPositions(sentence)
: returns an object with all the indices of the letters in a string -
map(array, callback)
: returns a new array based on the result of the callback function -
middle(arrayElements)
: returns an array with only the middle element(s) from the provided array -
tail(arrayElements)
: retrieves every element except the first element of an array -
takeUntil(array, callback)
: returns a slice of the array with elements taken from the beginning until the callback returns a truthy value -
without(sourceArray, itemsToRemove)
: removes specified items from an array and returns a new array without those items -
flatten(array)
: given an array with other arrays inside, it can flatten it into a single-level array
