what for?

you can check if two objects are from the same class without have them instantiated in the same running proccess, so you can for example check if a json decoded object is of certain class/type

check if two one dimensional objects are different

two same objects

console.log("test both objects same")
var o_1 = {n_a:2, n_b:3, o_c: {}, a_d: [0,2], s_x:"D"};
var o_2 = {n_a:2, n_b:3, o_c: {}, a_d: [0,2], s_x:"D"};
var a_o_missing_prop = f_a_o_missing_prop(o_1, o_2);
console.log(a_o_missing_prop)

object2 is different

console.log("test object 2 is missing some props")
var o_1 = {n_a:2, n_b:3, o_c: {}, a_d: [0,2], s_x:"D"};
var o_2 = {n_a:2,                 a_d: [0,2], s_x:"D"};
var a_o_missing_prop = f_a_o_missing_prop(o_1, o_2);
console.log(a_o_missing_prop)

object1 is different

console.log("test object 1 is missing some props")
var o_1 = {       n_b:3, o_c: {},             s_x:"D"};
var o_2 = {n_a:2, n_b:3, o_c: {}, a_d: [0,2], s_x:"D"};
var a_o_missing_prop = f_a_o_missing_prop(o_1, o_2);
console.log(a_o_missing_prop)

multidimensional objects

both objects same

console.log("test recursive, both objects same")
var o_1  = {
o_sub: {n_a:1, n_b:255, n_c:1}
}
var o_2  = {
o_sub: {n_a:2, n_b:3, n_c:44}
}
var a_o_missing_prop = f_a_o_missing_prop__recursive_in_first_arg_object(o_1, o_2);
console.log(a_o_missing_prop)

not same

console.log("test recursive, o_1.o_sub.n_b is existing, o_2.o_sub.n_b is missing")
var o_1  = {
o_sub: {n_a:2, n_b:3}
}
var o_2  = {
o_sub: {n_a:2, n_b:3, n_c:44}
}
var a_o_missing_prop = f_a_o_missing_prop__recursive_in_first_arg_object(o_1, o_2);
console.log(a_o_missing_prop)
