### IntelliSense
Visual Studio Code comes with powerful IntelliSense for JavaScript and TypeScript preinstalled. Other languages can be upgraded with better IntelliSense through one of the many [extensions](command:workbench.extensions.action.showPopularExtensions).
In the below example, position the text cursor in front of the error underline, right after the dot and press <spanclass="shortcut"data-command="editor.action.triggerSuggest"></span> to invoke IntelliSense.
