+name: Detect when code is executed with Bun
+---
+
+The recommended way to conditionally detect when code is being executed with `bun` is to check for the existence of the `Bun` global.
+
+This is similar to how you'd check for the existence of the `window` variable to detect when code is being executed in a browser.
+
+```ts
+if (typeof Bun !== "undefined") {
+  // this code will only run when the file is run with Bun
+}
+```
+
+---
+
+In TypeScript environments, the previous approach will result in a type error unless `bun-types` is globally installed. To avoid this, you can check `process.versions` instead.
+
+```ts
+if (process.versions.bun) {
+  // this code will only run when the file is run with Bun
+}
+```
