Install it:

npm install @gus.demoura/lotide

const _ = require('@gus.demoura/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): assert if two primitive values are equal
• assertArraysEqual(arr1, arr2): assert if two arrays are equal
• assertObjectsEqual(actual, expected): assert if two objects are equal
• countLetters(string): created an object that counts how many times each letter appears in giver string
• countOnly(allItems, itemsToCount): given an array, counts how many times itemsToCount appears in that array
• eqArrays(arr1, arr2): determine if two arrays are equal
• eqObjects(object1, object2): determine if two objects are equal
• findKeys(object, callback): return first key whose value matches callback condition
• findKeysByValue(object, value): return key whose value matches value in the argument and undefined if not found
• head(array): return the first item of an array
• letterPositions(sentence): return an object with character as keys and values as all the position that given character occour in a sentence
• map(array, callback): return new array where the condition callback is applied to all items of array of the argument
• middle(array): return new array containing the middle item(s) of given array. If given array has odd number of items returns one middle element, if even return both middle elements
• tail(array): returns array with all the items after the first one of given array
• takeUntil(array, callback): returns new array with items in same order of given array up to the element that satisfies the condition of the callback argument
• without(source, itemsToRemove): returns new array that does not contain items listed in itemsToRemove argument
