@aaron.timbol/lotide 中文文档教程
Lotide
Lodash 库的迷你克隆。
Purpose
注意:此库是出于学习目的而发布的。 它不旨在用于生产级软件。
这个项目是我创建和发布的,是我在 Lighthouse Labs 学习的一部分。
Usage
安装它:
npm install @aaron.timbol/lotide
需要它:
const _ = require('aaron.timbol/lotide' );
调用它:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
目前实现了以下功能:
assertArraysEqual(arr1, arr2)
: Will log a message indicating if arr1 is equivalent to arr2assertEqual(actual, expected)
: Will log a message indicating if actual is equivalent to expected - used to test the output of functions and their expected value(s)assertObjectsEqual(actual, expected)
: Will log a message indicating if the object in actual is equivalent to the object in expected - use to test output of functions and their expected object value(s)countLetters(str)
: Will return an object with each letter provided in str and the number of times it appears in that stringcountOnly(
allitems, itemsToCount`): Will return an object with a count of each name in object itemsToCount and the amount of times it appears in allitemseqArrays(arr1, arr2)
: Will evaluate if arr1 is equal to arr2 and return a booleaneqObject(object1, object2)
: Will evaluate if object1 is equal to object2 and return a booleanfindKey(obj, callback)
: Will loop through keys in an object until the condition indicated in callback is satisfied. If no key is found, undefined is returnedfindKeyByValue(obj, value)
: Goes through all the keys in an object and returns the first key that contains the value providedflatten(arr)
: Will evaluate arr, looping through one level of nested array, and will return a new array with no nested arrayshead(arr)
: Will return the first element in an arrayletterPositions(str)
: Will return an object with a count of how many times each letter appears in a stringmap(arr, callback)
: Imitates the .map() method for arrays in JSmiddle(arr)
: Will return the middle-most value(s) in an array whose length is above 2tail(arr)
: Returns all elements of an array except the first element in cases where arr.length is above 2takeUntil(arr, func)
: Collects items in an array until the func condition is meant, at which point, it will return all the values preceding that valuewithout(sourceArr, itemsToRemove)
: Will return the elements in sourceArr, not including those in itemsToRemove
Lotide
