Can two functions in a js file call each other?

Question

I would like to ask my seniors, I wrote two functions in a js file.
Both work fine when used alone, but when I call one within the other,
The called function doesn't work, why? The code is as follows:
function aa()
{
some code;
bb();
}function bb(){some code;}

There is no problem with the call. It can be called normally. As for whether it is not running because your previous code has stopped, you can send the complete code so that we can use it as a reference.
