Why can't I set a JavaScript function's name property?

Question

I am learning JavaScript and read that functions are like objects and can have properties set like this:

var person = function(){
}
person.name=\"John Smith\         


        

Answer 1

The name property is set by the Function constructor and cannot be overwritten directly. If the function is declared anonymous, it will be set to an empty string.

For example:

var test = function test() {};
alert(test.name); // Displays "test"
test.name = "test2";
alert(test.name); // Still displays "test"
