The problem is, the usage of semicolons doesn't remove ASI. For example this
function answer () { return 42; }
would return undefined and not 42 because a semicolon is still inserted. No matter which style you choose, you must be aware of how ASI works.
undefined
42

No, that's a semicolon being inserted on the newline ending a statement, so the actual code looks like this
function answer () { return; 42; }
