Calling a function with double parameters () in javascript -

-

anyone know happens when call function double ()

so 

get_separate_save_methods_function(url, false);

becomes

get_separate_save_methods_function(url, false)();

i've never seen before seems change false argument true, when remove () same argument becomes false. it's not code , i'm trying work out if mistake or has been done of purpose.

no, () doesn't change argument false true.

get_separate_save_methods_function(url, false)();

can used when 

get_separate_save_methods_function(url, false)

returns function. calls returned function.

given get_separate_save_methods_function name, not mistake it's hard tell more code.
