- There's no need in `;` at the end of code blocks and syntax structures that use them like `if { ... }`, `for { }`, `function f { }` and alike.
91-
- A Function Expression appears in the context of the statement: `let sayHi = value;`. It's not a code block. The semicolon `;` is recommended at the end of statements, no matter what is the `value`. So the semicolon here is not related to Function Expression itself in any way, it just terminates the statement.

Just loop over the object and `return false` immediately if there's at least one property.
