that most people are hesitant between Browserify and Webpack, while the latter is nearly seven points ahead of the former. 29% of users said they preferred to use the Babel module, but before that, we can speculate that one of the two tools was used to package their own modules. 16. What database do you use? This is one of the many issues that can benefit from collaborative editing. JQuery is still strong, with more than 50% votes. Most JavaScript developers vote for Lodash or underscore, whil

We can choose to enable the ES2016 adorner in Babel.import {withDecoratedData} from ‘...‘;// Decorate component using ES7 decorator ‘@‘@withDecoratedDataclass MyComponent extends Component { rend

. Even if the first parameter is a regular expression object, you can specify the second parameter: Var reg = new RegExp (/antzone/gi, "g "); The regular expression modifier specified by the second parameter will overwrite the modifier in the first parameter. Ii. Regular Expression of strings: The match (), replace (), search (), and split () methods related to regular expressions belong to string objects.ES2015 modified this. When calling these four methods, the RegExp object instance method is

votes.What frameworks have you used?Unsurprisingly, React and Angular are well ahead of other frameworks, with 22.8% of Backbone still in a safe position.Do you use ES6?Respondents were quite divided on the issue, with nearly 20% of people almost never using ES6, more than 10% of them only wrote ES6, nearly 30% of people used ES6 extensively, and nearly 40% of people used it occasionally.Do you know what features will be in the coming ES2016?Roughly

Stage 3:candidate (Candidate) – Proposal specification through review and collection of feedback from vendors Stage 4:finished (complete)--the proposal is ready to join the ECMAScript, but it may take longer to reach the browser or Nodejs ES2016 ES2016 proves the standardization process by adding two small functions: The array contains the ()

example, we used the ES2016 syntax and wanted to compile it in the ES2015 environment.

Await/async is one of the most important features of ES7, it is the best asynchronous solution for JS so far. Although not entered in the ES2016, but soon arrived, is now in Es-next Stage 4 phase. https://segmentfault.com/a/1190000007116715 Direct examples, such as we need to get in order: Product data => user Data => comment data old friend Ajax The traditional writing, no need to explain Get Product Data Ajax (' Products.json ', (products) => {

This article is mainly to share with you about the ES6 series of statement variables let and const, interested friends can refer to the content of this article Brief introduction Concept The first version of ES6, released in June 2015, is the official name of the ECMAScript 2015 Standard (ES2015). ES6 is both a historical noun and a generic term, meaning the next-generation standard for JavaScript after version 5.1, covering the ES2015, ES2016, ES201

the compilation process. These converters receive an abstract syntax tree and manipulate the code before it is translated into executable JavaScript. Codemix has tried to develop plugins such as static runtime type checking, closure cancellation, JAVASCRIPT health macros (hygienic macros). Babel not only tracks the progress of ES6, but also the ES7 or ES2016 test site. For example, it already supports async/await, making it easier for developers to
