海外TECH	DEV Community	ES6 Handbook	https://dev.to/vedanthb/es6-handbook-12bd	ES Handbook From var to const letIn ES you declare variables via var Such variables are function scoped their scopes are the innermost enclosing functions The behavior of varis occasionally confusing This is an example var x function func randomize if randomize var x Math random A scope whole function return x return x accesses the x from line A func false undefinedThat func returns undefined may be surprising You can see why if you rewrite the code so that it more closely reflects what is actually going on var x function func randomize var x if randomize x Math random return x return x func false undefinedIn ES you can additionally declare variables via let and const Such variables are block scoped their scopes are the innermost enclosing blocks let is roughly a block scoped version of var const works like let but creates variables whose values can t be changed letand constbehave more strictly and throw more exceptions e g when you access their variables inside their scope before they are declared Block scoping helps with keeping the effects of code fragments more local And it s more mainstream than function scoping which eases moving between JavaScript and other programming languages If you replace var with let in the initial version you get different behavior let x function func randomize if randomize let x Math random return x return x func false That means that you can t blindly replace var with let or const in existing code you have to be careful during refactoring My advice is Prefer const You can use it for all variables whose values never change Otherwise use let for variables whose values do change Avoid var From IIFEs to blocksIn ES you had to use a pattern called IIFE Immediately Invoked Function Expression if you wanted to restrict the scope of a variable tmp to a block function open IIFE var tmp ··· ··· close IIFEconsole log tmp ReferenceErrorIn ECMAScript you can simply use a block and a letdeclaration or a const declaration open block let tmp ··· ··· close blockconsole log tmp ReferenceError From concatenating strings to template literalsWith ES JavaScript finally gets literals for string interpolation and multi line strings String interpolationIn ES you put values into strings by concatenating those values and string fragments function printCoord x y console log x y In ES you can use string interpolation via template literals function printCoord x y console log x y Multi line stringsTemplate literals also help with representing multi line strings For example this is what you have to do to represent one in ES var HTML SKELETON lt doctype html gt n lt html gt n lt head gt n lt meta charset UTF gt n lt title gt lt title gt n lt head gt n lt body gt n lt body gt n lt html gt n If you escape the newlines via backslashes things look a bit nicer but you still have to explicitly add newlines var HTML SKELETON lt doctype html gt n lt html gt n lt head gt n lt meta charset UTF gt n lt title gt lt title gt n lt head gt n lt body gt n lt body gt n lt html gt ES template literals can span multiple lines const HTML SKELETON lt doctype html gt lt html gt lt head gt lt meta charset UTF gt lt title gt lt title gt lt head gt lt body gt lt body gt lt html gt From function expressions to arrow functionsIn current ES code you have to be careful with this whenever you are using function expressions In the following example I create the helper variable this line A so that the this of UiComponent can be accessed in line B function UiComponent var this this A var button document getElementById myButton button addEventListener click function console log CLICK this handleClick B UiComponent prototype handleClick function ··· In ES you can use arrow functions which don t shadow this line A function UiComponent var button document getElementById myButton button addEventListener click gt console log CLICK this handleClick A In ES you also have the option of using a class instead of a constructor function That is explored later Arrow functions are especially handy for short callbacks that only return results of expressions In ES such callbacks are relatively verbose var arr var squares arr map function x return x x In ES arrow functions are much more concise const arr const squares arr map x gt x x When defining parameters you can even omit parentheses if the parameters are just a single identifier Thus x gt x x and x gt x x are both allowed Handling multiple return valuesSome functions or methods return multiple values via arrays or objects In ES you always need to create intermediate variables if you want to access those values In ES you can avoid intermediate variables via destructuring Multiple return values via arraysexec returns captured groups via an Array like object In ES you need an intermediate variable matchObjin the example below even if you are only interested in the groups var matchObj d d d d d d d d exec var year matchObj var month matchObj var day matchObj In ES destructuring makes this code simpler const year month day d d d d d d d d exec The empty slot at the beginning of the Array pattern skips the Array element at index zero Multiple return values via objectsThe method Object getOwnPropertyDescriptor returns a property descriptor an object that holds multiple values in its properties In ES even if you are only interested in the properties of an object you still need an intermediate variable propDesc in the example below var obj foo var propDesc Object getOwnPropertyDescriptor obj foo var writable propDesc writable var configurable propDesc configurable console log writable configurable true trueIn ES you can use destructuring const obj foo const writable configurable Object getOwnPropertyDescriptor obj foo console log writable configurable true true From for to forEach to for ofPrior to ES you iterated over Arrays as follows var arr a b c for var i i lt arr length i var elem arr i console log elem In ES you have the option of using the Array method forEach arr forEach function elem console log elem A for loop has the advantage that you can break from it forEach has the advantage of conciseness In ES the for of loop combines both advantages const arr a b c for const elem of arr console log elem If you want both index and value of each array element for of has got you covered too via the new Array method entries and destructuring for const index elem of arr entries console log index elem Handling parameter default valuesIn ES you specify default values for parameters like this function foo x y x x y y ··· ES has nicer syntax function foo x y ··· An added benefit is that in ES a parameter default value is only triggered by undefined while it is triggered by any falsy value in the previous ES code From arguments to rest parametersIn ES if you want a function or method to accept an arbitrary number of arguments you must use the special variable arguments function logAllArguments for var i i lt arguments length i console log arguments i In ES you can declare a rest parameter args in the example below via the operator function logAllArguments args for const arg of args console log arg Rest parameters are even nicer if you are only interested in trailing parameters function format pattern args ··· Handling this case in ES is clumsy function format pattern var args slice call arguments ··· Rest parameters make code easier to read You can tell that a function has a variable number of parameters just by looking at its parameter definitions From function expressions in object literals to method definitionsIn JavaScript methods are properties whose values are functions In ES object literals methods are created like other properties The property values are provided via function expressions var obj foo function ··· bar function this foo trailing comma is legal in ES ES has method definitions special syntax for creating methods const obj foo ··· bar this foo From constructors to classesES classes are mostly just more convenient syntax for constructor functions Base classesIn ES you implement constructor functions directly function Person name this name name Person prototype describe function return Person called this name In ES classes provide slightly more convenient syntax for constructor functions class Person constructor name this name name describe return Person called this name Note the compact syntax for method definitions no keyword function needed Also note that there are no commas between the parts of a class Derived classesSubclassing is complicated in ES especially referring to super constructors and super properties This is the canonical way of creating a sub constructor Employee of Person Person call this name super name this title title Employee prototype Object create Person prototype Employee prototype constructor Employee Employee prototype describe function return Person prototype describe call this super describe this title ES has built in support for subclassing via the extends clause class Employee extends Person constructor name title super name this title title describe return super describe this title From custom error constructors to subclasses of ErrorIn ES it is impossible to subclass the built in constructor for exceptions Error The following code shows a work around that gives the constructor MyError important features such as a stack trace function MyError Use Error as a function var superInstance Error apply null arguments copyOwnPropertiesFrom this superInstance MyError prototype Object create Error prototype MyError prototype constructor MyError function copyOwnPropertiesFrom target source Object getOwnPropertyNames source forEach function propKey var desc Object getOwnPropertyDescriptor source propKey Object defineProperty target propKey desc return target In ES all built in constructors can be subclassed which is why the following code achieves what the ES code can only simulate class MyError extends Error From objects to MapsUsing the language construct object as a map from strings to arbitrary values a data structure has always been a makeshift solution in JavaScript The safest way to do so is by creating an objectwhose prototype is null Then you still have to ensure that no key is ever the string proto because that property key triggers special functionality in many JavaScript engines The following ES code contains the function countWords that uses the object dict as a map var dict Object create null function countWords word var escapedWord escapeKey word if escapedWord in dict dict escapedWord else dict escapedWord function escapeKey key if key indexOf proto return key else return key In ES you can use the built in data structure Map and don t have to escape keys As a downside incrementing values inside Maps is less convenient const map new Map function countWords word const count map get word map set word count Another benefit of Maps is that you can use arbitrary values as keys not just strings New string methodsThe ECMAScript standard library provides several new methods for strings From indexOf to startsWith if str indexOf x ESif str startsWith x ESFrom indexOfto endsWith function endsWith str suffix ES var index str indexOf suffix return index gt amp amp index str length suffix length str endsWith suffix ESFrom indexOf to includes if str indexOf x gt ESif str includes x ESFrom join to repeat the ES way of repeating a string is more of a hack new Array join ES repeat ES New Array methodsThere are also several new Array methods in ES From Array prototype indexOf to Array prototype findIndexThe latter can be used to find NaN which the former can t detect const arr a NaN arr indexOf NaN arr findIndex x gt Number isNaN x As an aside the new Number isNaN provides a safe way to detect NaN because it doesn t coerce non numbers to numbers gt isNaN abc true gt Number isNaN abc falseFrom Array prototype slice to Array from or the spread operatorIn ES Array prototype slice was used to convert Array like objects to Arrays In ES you have Array from var arr Array prototype slice call arguments ESconst arr Array from arguments ESIf a value is iterable as all Array like DOM data structure are by now you can also use the spread operator to convert it to an Array const arr abc a b c const arr new Set add a add b a b From apply to Array prototype fill In ES you can use apply as a hack to create in Array of arbitrary length that is filled with undefined Same as Array undefined undefined var arr Array apply null new Array undefined undefined In ES fill is a simpler alternative const arr new Array fill undefined undefined undefined fill is even more convenient if you want to create an Array that is filled with an arbitrary value ESvar arr Array apply null new Array map function x return x x x ESconst arr new Array fill x x x fill replaces all Array elements with the given value Holes are treated as if they were elements From CommonJS modules to ES modulesEven in ES module systems based on either AMD syntax or CommonJS syntax have mostly replaced hand written solutions such as the revealing module pattern ES has built in support for modules Alas no JavaScript engine supports them natively yet But tools such as browserify webpack or jspm let you use ES syntax to create modules making the code you write future proof Multiple exportsIn CommonJS you export multiple entities as follows lib js var sqrt Math sqrt function square x return x x function diag x y return sqrt square x square y module exports sqrt sqrt square square diag diag main js var square require lib square var diag require lib diag console log square console log diag Alternatively you can import the whole module as an object and access square and diag via it main js var lib require lib console log lib square console log lib diag Multiple exports in ESIn ES multiple exports are called named exports and handled like this lib js export const sqrt Math sqrt export function square x return x x export function diag x y return sqrt square x square y main js import square diag from lib console log square console log diag The syntax for importing modules as objects looks as follows line A main js import as lib from lib A console log lib square console log lib diag Single exportsNode js extends CommonJS and lets you export single values from modules via module exports myFunc js module exports function ··· main js var myFunc require myFunc myFunc In ES the same thing is done via a so called default export declared via export default myFunc js export default function ··· no semicolon main js import myFunc from myFunc myFunc I hope this blog helped you learn something new	2022-06-10 02:18:32
