Visual Studio Code includes multiple extensions for FTP, allowing the software to be used as a free alternative for web development. A notable feature is the ability to create extensions that add support for new languages, themes, and debuggers, perform static code analysis, and add code linters using the Language Server Protocol. This includes additions to the editor and language support. Visual Studio Code can be extended via extensions, available through a central repository. Many Visual Studio Code features are not exposed through menus or the user interface but can be accessed via the command palette. Unwanted files and folders can be excluded from the project tree via the settings.
It supports a number of programming languages and a set of features that differs per language.
This allows it to operate as a language-agnostic code editor for any language. Instead of a project system, it allows users to open one or more directories, which can then be saved in workspaces for future reuse. Visual Studio Code employs the same editor component (codenamed "Monaco") used in Azure DevOps (formerly called Visual Studio Online and Visual Studio Team Services). It is based on the Electron framework, which is used to develop Node.js Web applications that run on the Blink layout engine. Visual Studio Code is a source-code editor that can be used with a variety of programming languages, including Java, JavaScript, Go, Node.js, Python and C++.
