These features help you to learn more about the code you're using, keep track of the parameters you're typing, and add calls to properties and methods with only a few keystrokes. The files are downloaded to a cache located under the user folder at %LOCALAPPDATA%\Microsoft\TypeScript.IntelliSense is a code-completion aid that includes a number of features: List Members, Parameter Info, Quick Info, and Complete Word. d.ts file that describes the library in order to provide richer IntelliSense.

d.ts files, and the most common repository for such definitions is on DefinitelyTyped.īy default, the Salsa language service will try to detect which JavaScript libraries are in use and automatically download and reference the corresponding. In the TypeScript world, most popular JavaScript libraries have their APIs described by. d.ts file (see TypeScript documentation), and types such as interfaces and classes declared in TypeScript are available for use as types in JsDoc comments.īelow, we show a simple example of a TypeScript definition file providing such type information (via an interface) to a JavaScript file in the same project (using a JsDoc tag).Īutomatic acquisition of type definitions For example, JavaScript IntelliSense can be provided for values declared in a. IntelliSense based on TypeScript declaration filesīecause JavaScript and TypeScript are now based on the same language service, they are able to interact in a richer way. See JSDoc support in JavaScript for the JsDoc annotations currently supported. This.prop = param1 // "param1" (and thus "this.prop") are now of type "string".

CommonJS-style module patterns, specified as property assignments on the exports object, or assignments to the module.exports property.įoo.prototype.getIt = function () param1 - The first argument to this function.

"ES3-style" classes, specified using a constructor function and assignments to the prototype property.

d.ts files (see later sections).Īdditionally, there is special inference for the following: NextItem // now we know nextItem is a stringįor a function, the return type can be inferred from the return statements.įor function parameters, there is currently no inference, but there are ways to work around this using JSDoc or TypeScript. NextItem // here we know nextItem is a number Luckily, it is usually fairly easy to figure out a type given the surrounding code context.įor a variable or property, the type is typically the type of the value used to initialize it or the most recent value assignment. In JavaScript, most of the time there is no explicit type information available.

Automatic acquisition of type definitions.

IntelliSense based on TypeScript declaration files.

TypeScript uses several sources to build up this information: This new information is provided by the TypeScript language service, which uses static analysis behind the scenes to better understand your code. Starting in Visual Studio 2017, JavaScript IntelliSense displays a lot more information on parameter and member lists. What's new in the JavaScript language service in Visual Studio 2017 See the VS Code docs for more info.įor more information about the general IntelliSense functionality of Visual Studio, see Using IntelliSense. The new editing experience also mostly applies to Visual Studio Code. Details are included in this article, and you can also read this blog post. Starting in Visual Studio 2017, the JavaScript language service uses a new engine for the language service (called "Salsa").
