+# Migrate legacy `app.del()` to `app.delete()`
+
+Migrates usage of the legacy APIs `app.del()` to `app.delete()`.
+Initially, `del` was used instead of `delete`, because `delete` is a reserved keyword in JavaScript. However, as of ECMAScript 6, `delete` and other reserved keywords can legally be used as property names. The `app.del()` method was deprecated in Express 4 and removed in Express 5. 
+
+## Example
+
+### Migrating `app.del()`
+
+The migration involves replacing instances of `app.del()` with `app.delete()`.
+
+```diff
+- app.del('/some-route', (req, res) => {
++ app.delete('/some-route', (req, res) => {
+    // Some logic here
+ });
+```
+
+## References
+
+- [Migration of app.del()](https://expressjs.com/en/guide/migrating-5.html#app.del)
