To execute the function immediately, wrap it in parentheses and call it like this:
if((function(){return false;})() || false) {alert('true');}
Example: https://jsfiddle.net/Ar14/7p2ompod/
Utilize the .call() method provided by the function constructor:
if(function(){return false;}.call() || false) { alert('true'); }
An added benefit of using this approach is the ability to pass variables to the function, for example:
if(function(){return arguments[0] == 7;}.call(null, 7) === true) alert('yes, it is 7');
