(you meant to call the function: if (Math.random()<0.5) {holder=false;}

Your code is not equivalent to assignment you dislike.  You'd need
something like

 if (Math.random()<0.5) holder=false; else holder=true;

But what do you think the "Math.random() < 0.5" in the "if" is if not an
expression yielding a true/false result?  And if that is what it is, why
not allow the result to be assigned just like the result of any pther
expression?

Many decades ago, before we knew how to do this stuff, there were
programming languages that only allowed relations and comparisons in
certain positions (the test of an "if" or a "while" etc.) but thankfully
those days are long gone.
