A word summary: using Webstorm's own file Watcher function +babel to achieve automatic conversion ECMAScript 6 code for ES5 code1.Create a new empty Project, and then create a new main.js in the SRC directory;This step is not necessary, just get started.

Explore ES6 Proxy in detail, explore es6proxy Preface In ES6, the Proxy constructor is an accessible global object.

1. PrefaceBecause the ES6 syntax is supported on various browsers, some browsers have a high degree of support for ES6 syntax, and some browsers support low, so in order to be compatible with most browsers, we need to use the Babel compiler to compile the ES6 syntax in the code into ES5 syntax when using ES6 syntax.

ES6 Core FeaturesBlock-level scopes Let: the existence of a block-level scope for a declared variable does not declare advanceES5// declare ahead of var x = ' outer '; function Test (inner) { if (inner) { var x = ' inner '; Console.log (x); } Console.log (x);} Test (false//Test (true) // inner inner ES6// declaration does not advance let x = ' outer '; function Test (inner) {

Afternoon read a chapter ECMA-262 by Dmitry Soshnikov, now a little to summarize the parameters in the ES6 in the default values and the resulting parameter intermediate scope. Original address: http://dmitrysoshnikov.com/ecmascript/es6-notes-default-values-of-parameters/# Conditional-intermediate-scope-for-parametersParameter default values in ES6 are similar to

I was amazed by the simplicity of the code, which was contacted by Coffeescript in 15. I wrote JavaScript before, but found it too redundant and basically no motivation to continue writing. 16 began to contact react and react Native, also formally understand the ES6 grammar, found it and coffeescript very close, and has a great improvement. These days refer to http://es6-features.org/, to

Es6 notes 5 ^_^ set, map, iterator, es6iteratorI. set1. basic usage The data structure Set is similar to an array, but the Member values are unique without repeated values. Let s = new Set (); [2, 3, 5, 4, 5, 2]. map (x => s. add (x) for (let I of s) {console. log (I)} // 2 3 5 4 // The Set function accepts an array as a parameter for initialization. Var items = new Set ([1, 2, 3, 4, 5, 5]); console. log (items); // set object console. log (items. siz

Deeply Understand how es6 creates this component in React, reactes6 Started at: https://mingjiezhang.github.io /. In JavaScript, this object is bound to a function-based execution environment (that is, context) during runtime. Starting with the demo in react In the last react update, Facebook added the class in es6 to the component creation method. Facebook also recommends that you define a Component class

The introduction of a new string literal-template string in ES6, in addition to using inverted quotation marks ('), means that they do not appear to be any different from ordinary strings. In the simplest case, they are ordinary strings: Context.filltext (' Ceci n ' est pas une cha?ne. ', x, y); Context.filltext (' Ceci n ' est pas une cha?ne. ', x, y); It is called a template string because the template string is a simple string inter

First, let and const Let: declaring a variable that works only within declared block-level scopes (curly braces) [Note: Let does not automatically ascend to Var] If there is a let or const command in a block, the block is resolved into a closed scope (temporary dead zone, which must be declared and reused) [so that if there is a let in a block, there may be a dead zone, there may be errors in the use order of variable declarations] Let has added block-level scope to JavaScript Functions decl

Sometimes it is really troublesome to write more variables, and a lot of tedious and similar repetitive work, es6 provides us with a variety of more convenient forms of declaring variables-deconstruct and assignment of variables. The following article describes the information about variable deconstruct assignment in ES6. For more information, see. Sometimes it is really troublesome to write more variables,
