I'm looking for another way of doing the following:

function call_any_function(func, parameters){
    // func => any given function
    if(parameters.length==0){ func(); }    
    if(parameters.length==1){ func(parameters[0]); }    
    if(parameters.length==2){ func(parameters[0], parameters[1]); }    
    if(parameters.length==3){ func(parameters[0], parameters[1], parameters[2]); }    
    if(parameters.length==4){ func(parameters[0], parameters[1], parameters[2], parameters[3]); }
    // ... and so on
};

It seems basic but I couldn't find an answer.

Any ideas?
