Check for false

Question

Is there any better way of doing this?

if(borrar() !== false)
{
    alert(\'tatatata bum bum bum prapra\');
}
return false;

Answer 1

If you want to check for false and alert if not, then no there isn't.

If you use if(val), then anything that evaluates to 'truthy', like a non-empty string, will also pass. So it depends on how stringent your criterion is. Using === and !== is generally considered good practice, to avoid accidentally matching truthy or falsy conditions via JavaScript's implicit boolean tests.
