Question

Today I’ve received a small ActionScript 3 application that I need to have a look at and make some changes to.

I’ve noticed that the entire application is riddled with the return keyword, eg:

// Constructor
public function MyClass()
{
    // some logic

    return;
}

public function someFunction():void
{
    // some logic

    return;
}

Is there a possible reason for this, or is the developer who worked on this using some weird, self-taught practice?

Answer 1

return can end a function early if condition is met, the appropriate information has been assigned or passed, etc. while the function has additional code that is not needed, but if all of the void functions just have return at the end of the function then they are redundant.
