let Object_A = {};
Object_A.Func_01 = function() {
console.log("Hello World");
}
console.log(Object_A.Func_01());

`console.log` does not return anything, it just shows its value in the console – Parzh from Ukraine May 27 '21 at 11:43

3Because the function doesn't return anything so logging "no return value" is `undefined`. – Niet the Dark Absol May 27 '21 at 11:43

because `Func_01` doesn't return anything and you're logging the return value of the function. – DecPK May 27 '21 at 11:43

It's because by saying console.log(object.function()) you are printing the return value of the function (which is undefined because you haven't returned anything specifically). If you want to just print the hello word it's enough to call the function object.function() cause it is already doing that.
