#VISUAL STUDIO FOR MAC JAVASCRIPT SUPPORT CODE#

Visual Studio Code is a lightweight but powerful source code editor that runs on your desktop and is available for Windows, MacOS, and Linux. Let’s take a look at the capabilities and the trade-offs of these two development tools. Your choice may depend as much on your work style as on the language support and features you need. While Visual Studio Code is highly configurable, Visual Studio is highly complete. Still, choosing between Visual Studio Code and Visual Studio is not as simple as choosing between lightweight editor and heavyweight IDE. Still, even updating a dozen extensions in Visual Studio Code takes much less time than Visual Studio takes to rebuild the symbol tables of a large C++ project. I said usually, not always: Visual Studio Code itself needs a monthly update, and the many extensions I have installed often need their own updates. Visual Studio Code usually starts up quickly enough that I can be productive in a few minutes, even for large projects. These days, I don’t feel the need to open my code projects first thing every morning, or to keep them open all day.

When I worked on a C++ project with ~2 million lines of code, I also jump-started each day’s work by automatically running a batch script that did a code checkout and full rebuild of the product in the wee hours. I would keep the IDE open all day as I went through develop/test/debug cycles to avoid another startup delay. ts files.For decades, when I got to work in the morning, I would start Microsoft Visual Studio (or one of its predecessors, such as Visual C++ or Visual InterDev), then brew tea and possibly attend a morning meeting while it went through its laborious startup. These type checks also enable some exciting Quick Fixes for JavaScript, including Add missing import and Add missing property. This is a great way to catch common programming mistakes. VS Code allows you to leverage some of TypeScript's advanced type checking and error reporting functionality in regular JavaScript files. See the documentation for tsconfig.json here to see other available options. Note: jsconfig.json is the same as a tsconfig.json file, only with allowJs set to true. For more information, see Migrating from JavaScript. To start migrating to TypeScript, rename your jsconfig.json file to tsconfig.json and set the allowJs property to true.

It is possible to have mixed TypeScript and JavaScript projects. Note that file paths in exclude and include are relative to the location of jsconfig.json.įor more information, see the full jsconfig.json documentation. The best practice, and least error prone route, is to use the include attribute with a single src folder. Type declaration files are automatically downloaded and managed by Visual Studio Code for packages listed in your project's package.json or that you import into a JavaScript file. In this image you can see IntelliSense, including the method signature, parameter info, and the method's documentation for the popular lodash library.

For libraries that do not include typings, VS Code's Automatic Type Acquisition will automatically install community maintained typings file for you.Īutomatic type acquisition requires npmjs, the Node.js package manager, which is included with the Node.js runtime.

Many popular libraries ship with typings files so you get IntelliSense for them automatically. Type declaration files are written in TypeScript so they can express the data types of parameters and functions, allowing VS Code to provide a rich IntelliSense experience in a performant manner. IntelliSense for JavaScript libraries and frameworks is powered by TypeScript type declaration (typings) files. In addition to objects, methods, and properties, the JavaScript IntelliSense window also provides basic word completion for the symbols in your file. This document describes the JSDoc annotations currently supported. When type inference does not provide the desired information, type information may be provided explicitly with JSDoc annotations.

While IntelliSense should just work for most JavaScript projects without any configuration, you can make IntelliSense even more useful with JSDoc or by configuring a jsconfig.json project.įor the details of how JavaScript IntelliSense works, including being based on type inference, JSDoc annotations, TypeScript declarations, and mixing JavaScript and TypeScript projects, see the JavaScript language service documentation. Our JavaScript IntelliSense is powered by the JavaScript language service developed by the TypeScript team. Visual Studio Code's JavaScript IntelliSense provides intelligent code completion, parameter info, references search, and many other advanced language features. Using the TypeScript language service, VS Code can provide smart completions (IntelliSense) as well as type checking for JavaScript. This topic describes some of the advanced JavaScript features supported by Visual Studio Code.
