A reference directive enables Visual Studio to establish a relationship between the script you are currently editing and other scripts. The reference directive lets you include a script file in the scripting context of the current script file. This enables IntelliSense to reference externally defined functions, types, and fields as you code. Visual Studio 2019 includes improved support for the Vue.js framework, which improves the development experience when creating an application with Vue.js, JavaScript.
