Intellisense in visual studio code 5 gases emitted from the exhaust pipe

VS Code IntelliSense features are powered by a language service. A language service provides intelligent code completions based on language semantics and an analysis of your source code. If a language service knows possible completions, the IntelliSense suggestions will pop up as you type. If you continue typing characters, the list of members (variables, methods, etc.) is filtered to include only members containing your typed characters. Pressing Tab or Enter will insert the selected member.

As provided by the language service, you can see quick info for each method by either pressing ⌃Space (Windows, Linux Ctrl+Space) or clicking the info icon. The accompanying documentation for the method will now expand to the side. The expanded documentation will stay so and will update as you navigate the list. You can close this by pressing ⌃Space (Windows, Linux Ctrl+Space) again or by clicking on the close icon.

When applicable, a language service will surface the underlying types in the quick info and method signatures. In the image above, you can see several any types. Because JavaScript is dynamic and doesn’t need or enforce types, any suggests that the variable can be of any type. Types of completions

The JavaScript code below illustrates IntelliSense completions. IntelliSense gives both inferred proposals and the global identifiers of the project. The inferred symbols are presented first, followed by the global identifiers (shown by the document icon).

// Controls if suggestions should be accepted on ‘Enter’ – in addition to ‘Tab’. Helps to avoid ambiguity between inserting new lines or accepting suggestions. The value ‘smart’ means only accept a suggestion with Enter when it makes a textual change "editor.acceptSuggestionOnEnter": "on",

By default, VS Code shows snippets and completion proposals in one widget. You can control the behavior with the editor.snippetSuggestions setting. To remove snippets from the suggestions widget, set the value to "none". If you’d like to see snippets, you can specify the order relative to suggestions; at the top ( "top"), at the bottom ( "bottom"), or inline ordered alphabetically ( "inline"). The default is "bottom". Suggestion selection

By default, VS Code pre-selects the previously used suggestion in the suggestion list. This is very useful as you can quickly insert the same completion multiple times. If you’d like different behavior, for example, always select the top item in the suggestion list, you can use the editor.suggestSelection setting.

When using the last option, recentlyUsedByPrefix, VS Code remembers which item was selected for a specific prefix (partial text). For example, if you typed co and then selected console, the next time you typed co, the suggestion console would be pre-selected. This lets you quickly map various prefixes to different suggestions, for example co -> console and con -> const. Key bindings

If you find IntelliSense has stopped working, the language service may not be running. Try restarting VS Code and this should solve the issue. If you are still missing IntelliSense features after installing a language extension, open an issue in the repository of the language extension.

A particular language extension may not support all the VS Code IntelliSense features. Review the extension’s README to find out what is supported. If you think there are issues with a language extension, you can usually find the issue repository for an extension through the Marketplace. Navigate to the extension’s detail page and click the Support link. Next Steps

A: This issue is caused by missing type declaration (typings) files in JavaScript. You can check if a type declaration file package is available for a specific library by using the TypeSearch site. There is more information about this issue in the JavaScript language topic. For other languages, please consult the extension’s documentation.
