How to fire multiple JavaScript functions at once -

how fire these 4 functions @ same time;

firethisnow1(); firethisnow2(); firethisnow3(); firethisnow4(); 

you mean asynchronously yes? try this:

settimeout(function(){     firethisnow1(); }, 0);  settimeout(function(){     firethisnow2(); }, 0);  settimeout(function(){     firethisnow3(); }, 0);  settimeout(function(){     firethisnow4(); }, 0); 

same (if parent object window):

for(var = 1; < 5; i++){     settimeout(function(){         window['firethisnow' + i]();     }, 0); }
