JavaScript projects (jsconfig.json)Ī jsconfig.json file defines a JavaScript project in VS Code. See Working with JavaScript for information about VS Code's JavaScript IntelliSense, how to configure it, and help troubleshooting common IntelliSense problems. VS Code provides IntelliSense within your JavaScript projects for many npm libraries such as React, lodash, and express and for other platforms such as node, serverless, or IoT. Sorry, your browser doesn't support HTML 5 video. IntelliSense shows you intelligent code completion, hover information, and signature information so that you can write code more quickly and correctly. For a more in-depth guide on how these features work and can be configured, see Working with JavaScript. Extensions from the VS Code Marketplace can augment or change most of these built-in features. This page summarizes the JavaScript features that VS Code ships with. Most of these features just work out of the box, while some may require basic configuration to get the best experience. Visual Studio Code includes built-in JavaScript IntelliSense, debugging, formatting, code navigation, refactorings, and many other advanced language features. Configure IntelliSense for cross-compiling.ES6 does not allow accessing this in any way before calling super() within a child class constructor, while Haxe allows calling super() at any place in the constructor.Įven when we don't explicitly access this before super() in Haxe code, it can still happen when a class has fields with initializer values. One of significant differences between Haxe classes and ES6 classes reveals itself when inheritance is used. Accessing this before calling super constructors To enable ES6 generation mode, simply add -D js-es=6 to the compiler arguments.
This might be required when using third-party ES6 libraries, because native ES6 classes cannot be extended using the old method. Starting with Haxe 4.0, Haxe can generate ES6 class definitions instead of classic function + prototype combination. 12.2.2 ECMAScript 6 class generation since Haxe 4.0
