# \[WEBPACK] Một cách phân biệt khi bundle ra es5 hay es6 một ví dụ sử dụng webpack (ok) Đọc thêm: {% embed url="" %} public Method (y) ``` // Global module var myModule = (function ( jQ, _ ) { function privateMethod1(){ jQ(".container").html("test"); } function privateMethod2(){ console.log( _.min([10, 5, 100, 2, 1000]) ); } return{ publicMethod: function(){ privateMethod1(); } }; // Pull in jQuery and Underscore })( jQuery, _ ); myModule.publicMethod(); ``` C:\xampp\htdocs\webpack-demo\src\index.js ``` class Car { constructor(name, year) { this.name = name; this.year = year; } } var myCar = new Car("Ford", 2014); document.getElementById("demo").innerHTML = myCar.name + " " + myCar.year; ``` C:\xampp\htdocs\webpack-demo\index.html ``` Document

Demo

``` C:\xampp\htdocs\webpack-demo\package.json ``` { "name": "webpack-demo", "version": "1.0.0", "description": "", "private": true, "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "build": "webpack --mode production" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": { "webpack": "^5.17.0", "webpack-cli": "^4.4.0" }, "dependencies": { "babel-preset-es2015": "^6.24.1", "lodash": "^4.17.20" } } ``` C:\xampp\htdocs\webpack-demo\dist\main.js Với Es5 ``` const path = require('path'); module.exports = { entry: './src/index.js', target: ['web', 'es5'], output: { filename: 'main.js', path: path.resolve(__dirname, 'dist') } }; ``` ``` ! function() { var e = new class { constructor(e, n) { this.name = e, this.year = n } }("Ford", 2014); document.getElementById("demo").innerHTML = e.name + " " + e.year }(); ``` Với Es6 ``` const path = require('path'); module.exports = { entry: './src/index.js', target: ['web', 'es6'], output: { filename: 'main.js', path: path.resolve(__dirname, 'dist') } }; ``` ``` (() => { var e = new class { constructor(e, n) { this.name = e, this.year = n } }("Ford", 2014); document.getElementById("demo").innerHTML = e.name + " " + e.year })(); ``` Xem lại cách viết này đều là giống nhau chi tiết đọc ``` ! function(){}() && (() => {})() ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
