+#### Q - What will be the output of the below code and why
+
+```js
+const number = 1
+const result = (function (number) {
+  delete number
+  return number
+})(10)
+console.log(result)
+```
+
+#### Ans - The output of the above code is 10
+
+#### Explanations
+
+In this code, we are passing the value 10 as the input to the function. But again inside the function number is just a local primitive type of variable so delete will not make any changes to the number and the value 10 passed to the function will be returned from the function.
