Question

How can you get the type of arguments passed to a function?

Answer 1

Using typeof operator, we can get the type of arguments passed to a function. For example −

function func(x){

   console.log(typeof x, arguments.length);

}

func();                //==> "undefined", 0

func(1);               //==> "number", 1

func("1", "2", "3");   //==> "string", 3
