IntelliSense encompasses a variety of code editing functionalities, such as code completion, parameter information, quick insights, and member lists. These features may also be referred to by different names including "code completion," "content assist," and "code hinting." In Visual Studio Code, IntelliSense is readily available for languages like JavaScript, TypeScript, JSON, HTML, CSS, SCSS, and Less. Although VS Code inherently supports word-based completions for any programming language, users can enhance their IntelliSense experience by adding specific language extensions. The IntelliSense capabilities in VS Code are driven by a language service, which delivers smart code completions based on the semantics of the language and a thorough examination of your source code. When a language service identifies potential completions, IntelliSense suggestions appear dynamically as you type. As you continue to input characters, the suggestions for members—such as variables and methods—are filtered to show only those that match your input. This makes coding more efficient and intuitive, allowing developers to focus on logic rather than syntax.
