I haven't been following the thread in detail, but the simple answer to that
question is they don't, and they can't.
Fundamental JavaScript operations are reliable. It would take a major
breakdown of the JavaScript interpreter to get both an "if" and associated
"else" block to execute in the same pass through the code.
If it looks like that is happening, it's a safe bet that the problem is
really something else.
If you're not sure about something like this, add console.log calls to trace
through the code:
console.log( 'before if/else statement' );
if( condition ) {
console.log( 'inside if statement' );
}
else {
console.log( 'inside else statement' );
}
console.log( 'after if/else statement' );
When you run that code, you will always see this sequence:
before if/else statement
inside if statement
after if/else statement
Or this one:
before if/else statement
inside else statement
after if/else statement
You will *never* see this:
before if/else statement
inside if statement
inside else statement
after if/else statement
It just won't happen.
