+# Linting JavaScript in Visual Studio
+
+Linting JavaScript and TypeScript in Visual Studio is powered by [ESLint](https://eslint.org/). If you're new to ESLint, you can begin by checking their [documentation](https://eslint.org/docs/latest/user-guide/getting-started).
+
+## Enabling linting support
+
+To enable linting support in Visual Studio 2022 or later versions, enable the **Enable ESLint** setting in **Tools > Options > Text Editor > JavaScript/TypeScript > Linting**.
+
+:::image type="content" source="media/vs-2022/linting-tools-options.png" alt-text="Screenshot of linting Tools Options page.":::
+
+In the options page, you can also modify the set of files that you want to lint. By default, all file extensions that can be linted (*.js*, *.jsx*, *.ts*, *.tsx*) will be linted.
+
+You can override these options in some project types, like the [standalone React project templates](../javascript/tutorial-create-react-app.md). In these projects, you can override the settings from the **Tools > Options** page using project properties:

+
+## Installing ESLint dependencies
+
+Once linting is enabled, the necessary dependencies need to be installed. Dependencies include the [ESLint `npm` package](https://www.npmjs.com/package/eslint) and other plugins applicable to your project. This package can be installed locally in each project where you want to enable linting, or you can install it globally using `npm install -g eslint`. However, a global installation isn't recommended because plugins and shareable configs always need to be installed locally.
+
+Depending on the files you want to lint, other [ESLint plugins](https://eslint.org/docs/latest/user-guide/configuring/plugins) may be needed. For example, you may need [TypeScript ESLint](https://typescript-eslint.io/), which enables ESLint to run on TypeScript code and includes rules that are specific to the extra type information.
+
+When ESLint is enabled but the ESLint `npm` package isn't found, a gold bar is displayed that allows you to install ESLint as a local `npm` development dependency.
+
+:::image type="content" source="media/vs-2022/no-package-goldbar.png" alt-text="Screenshot of Install ESLint gold bar.":::
+
+Similarly, when an *.eslintrc* file isn't found, a gold bar is displayed to run a configuration wizard that will install the plugins applicable to the current project.
+
+:::image type="content" source="media/vs-2022/no-config-goldbar.png" alt-text="Screenshot of Run ESLint wizard gold bar.":::
+
+## Disabling linting rules and auto-fixes
+
+You can disable linting errors on a [specific line or file](https://eslint.org/docs/latest/user-guide/configuring/rules#disabling-rules). You can disable the errors by using the Quick Actions lightbulb menu:
+
+:::image type="content" source="media/vs-2022/code-actions.png" alt-text="Screenshot of linting Quick Actions.":::
+
+The following illustration shows the result if you disable a linting error for the selected line of code.
+
+:::image type="content" source="media/vs-2022/disabled-rule.png" alt-text="Screenshot of disabled linting rule.":::
+
+In addition, auto-fix code actions allow you to apply an auto-fix to address the respective linting error.
+
+## Troubleshooting
+
+You can open the **ESLint Language Extension** pane in the Output window to see any error messages or other logs that might explain the problem.
