+## Absolute Imports
+
+You can configure your application to support importing modules using absolute paths. This can be done by configuring a `jsconfig.json` or `tsconfig.json` file in the root of your project. If you're using TypeScript in your project, you will already have a `tsconfig.json` file.
+
+Below is an example `jsconfig.json` file for a JavaScript project. You can create the file if it doesn't already exist:
+
+```json
+{
+  "compilerOptions": {
+    "baseUrl": "src"
+  },
+  "include": ["src"]
+}
+```
+
+If you're using TypeScript, you can configure the `baseUrl` setting inside the `compilerOptions` of your project's `tsconfig.json` file.
+
+Now that you've configured your project to support absolute imports, if you want to import a module located at `src/components/Button.js`, you can import the module like so:
+
+```js
+import Button from 'components/Button';
+```
+
+For more information on these configuration files, see the [jsconfig.json reference](https://code.visualstudio.com/docs/languages/jsconfig) and [tsconfig.json reference](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) documentation.
