Discussion: Arrow Functions vs Traditional Functions

The style guide recommends using arrow functions for anonymous functions (Section 8.1). While I agree with this recommendation, I think it would be helpful to add more examples showing when traditional functions might still be preferred, such as:

1. When you need the function to be hoisted
2. When you need to use `this` binding differently
3. When you need the `arguments` object

What do you think about adding these clarifications?

Start with Section 8.1 of the JavaScript style guide and review the discussion for the requested clarifications. Done means the guide explains when traditional functions may be preferred for hoisting, `this` binding, and the `arguments` object, with examples for those cases.
