Yet again , Thanks for such a great article yogesh ... May i know how it is treated as no reassignment of number in this case .... as number is declared with const ... Thanks :)

```
const number = 1;

const result = (function (number) {
  delete number;
  return number;
})(10);
```

[kishore kumar](https://hashnode.com/@kch) `const` is considered as block scoped.

We can declare a `const` variable with the same name in different blocks. Declaring a function creates a separate block scope so there is no reassignment error
