method();

Its it possible to call a function without the brackets?e.g:

var call=method;

i have seen script like that, but i dont knw why!

the you wouldn't be calling it. that's part of their significance. In your snippet, if method is a function object, then call is now equal to the value of method.i.e.

var method = function(){  alert('sup');};var call = method;call();  //alerts 'sup'

No, you cannot call a function without the parens. When you use a function name without the parens, you are simply using a reference to the function. Script like what you posted assigns the reference to another variable. You could then use that variable name to call the function too.

function someFunction(msg) {   alert(msg);}var showMsg = someFunction;//Either of these will workshowMsg('This is a test.');someFunction('This is a test.');

I can't think of any specific examples right now of where this would be useful, but perhaps someone else might pop in and provide a few.
