![]() ![]() 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. Configure IntelliSense for cross-compiling.A directive's job is to reactively apply updates to the DOM when the value of its expression changes. Vue provides a number of built-in directives, including v-html and v-bind which we have introduced above.ĭirective attribute values are expected to be single JavaScript expressions (with the exception of v-for, v-on and v-slot, which will be discussed in their respective sections later). Directives ĭirectives are special attributes with the v- prefix. You can, however, explicitly define additional globals for all Vue expressions by adding them to. Globals not explicitly included in the list, for example user-attached properties on window, will not be accessible in template expressions. The list exposes commonly used built-in globals such as Math and Date. Template expressions are sandboxed and only have access to a restricted list of globals. Functions called inside binding expressions will be called every time the component updates, so they should not have any side effects, such as changing data or triggering asynchronous operations.
